As typical heteroaromatic compounds, thiophene is an air pollutant that pose serious environmental and health related impacts due to its volatility and toxicity. This work reports a hybrid process of absorption combined with electrochemical oxidation to degrade thiophene. The ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BF4) was employed as the absorbent to capture thiophene from air stream. Linear sweep voltammetry (LSV) demonstrated that thiophene could be oxidized on β-PbO2 anode modified with fluoride at 1.28 V versus Ag/Ag + electrode (RE) with a scan rate of 100 mV/s while [BMIM]BF4 was used as the electrolyte. Results of bulk electrolysis showed that thiophene could be thoroughly degraded within 60 min in [BMIM]BF4 under 50 mA/cm2 due to the successive attack of hydroxyl radicals (·OH) produced by electrolysis on the surface of β-PbO2 anode. Acetic acid was determined as the main intermediate and could be further mineralized to fumaric acid, maleic acid and oxalic acid, while sulfur atom in thiophene was finally converted to sulfate ions (SO42−). Based on the HPLC analysis and a precipitation of BaSO4, degradation pathway of thiophene was proposed and the thiophene sulfur could be degraded completely into sulfate. The kinetics of the electrochemical oxidation process for thiophene can be described by the pseudo-first order model. This absorption-electrochemical oxidation method with continuous operation would be a promising way for the clean and safe removal of heteroaromatic compounds from waste gases.

The present work addresses the assessment of human health risk from soil contaminated with total petroleum hydrocarbons (TPHs) due to crude oil pollution, with a particular focus on the polycyclic aromatic hydrocarbon (PAH) group of carcinogenic and toxic substances. Given that the measured risk for human health exceeded the accepted level, the study considered an electrochemical remediation method. The laboratory-scale experiments were conducted by using an electric field-based treatment as a possible solution for the remediation of contaminated soil. After 20 days of treatment, while the voltage applied was 15 V (specific voltage of 1 V/cm), the hydrocarbon content was significantly reduced. The parameters measured to determine the overall remediation efficiency were pH, redox potential, ionic strength, soil characteristics, voltage gradient, and zeta potential. The remediation degree observed during the experiments was around 50% for TPHs and 46% for PAHs. The applied remediation method resulted in significant removal efficiency of the tested contaminants from the soil. Consequently, the human health risk assessment for the new degree of contaminants in the soil was achieved. This data demonstrated to what extent the application of the remediation applied technology ensured an acceptable risk under the same exposure conditions for the industrial workers.

Three-dimensional NixCo3-xO4 nanowire arrays (NWAs) grown on carbon fiber cloth (CFC) are successfully fabricated by a simple hydrothermal method combined with a post annealing treatment, which are directly applied as binder-free electrodes for urea oxidation reaction (UOR). Remarkably, the Ni1.5Co1.5O4 NWAs/CFC sample shows much higher catalytic activity, lower overpotential, better stability towards urea electro-oxidation compared to NiO synthesized by the similar procedure. The Ni1.5Co1.5O4 electrode delivers a current density of 98.5 mA cm-2 mg-1 at 0.45 V (vs. Ag/AgCl) in 1 M KOH and 0.33 M urea electrolyte after 8-hour test. These nickel cobalt oxides electrodes with advanced architecture and desirable catalytic performance show great potential for the applications of urea electro-oxidation, including wastewater remediation, hydrogen production, sensors, and fuel cells.

With the popularity of ammonia fuel cell, nitrogen-containing compounds are becoming an alternative energy sources. However, most of those nitrogen compounds, especially ammonia, are dispersed in domestic wastewater and their treatment is often energy consumption. Therefore, the nitrogen retrieval from wastewater is becoming urgently needed of development. Adopting a new five-compartment electrodeionization technology, this paper demonstrates the possibility to concentrate ammonia nitrogen in synthetic wastewater. The result indicates that the optimum current is 0.18 A in artificial domestic sewage with low concentration ammonium ions among 15 mg/L. The nitrogen concentration can be enriched for about 12 times in single stage. The removal rate of nitrogen can reach over 90% with energy consumption of 19.104 g/kW·h. It explores a feasibility of recovering the ammonia nitrogen in wastewater.

The recovery of heavy metals from aqueous solutions or e-wastes is of upmost importance. Retrieval of Au, Ag, and Cu with electricity generation through building an ethanol-metal coupled redox fuel cells (CRFCs) is demonstrated. The cell was uniquely assembled on PdNi/C anode the electro-oxidation of ethanol takes place to give electrons and then go through the external circuit reducing metal ions to metallic on the cathode, metals are recovered. Taking an example of removal of 100mgL gold in 0.5M HAc-NaAc buffer solution as the catholyte, 2.0M ethanol in 1.0M alkaline solution as the anolyte, an open circuit voltage of 1.4V, more than 96% of gold removal efficiency in 20h, and equivalent energy production of 2.0kWhkg of gold can be readily achieved in this system. When gold and copper ions coexist, it was confirmed that metallic Cu is formed on the cathodic electrode later than metallic Au formation by XPS analysis. Thus, this system can achieve step by step electrodeposition of gold and copper while the two metal ions coexisting. This work develops a new approach to retrieve valuable metals from aqueous solution or e-wastes.

Conversion of chemical energy from wastewater into electrical energy is receiving more and more attention. By selecting hydrogen-rich or nitrogen-containing pollutants as the fuels and oxidative contaminants as the oxidants, coupled redox fuel cells (CRFCs) were designed. Based on our previous work, we presented several typical fuel cells, namely the ethanol-Cr(VI), urea/urine-Cr(VI), NaBH4-Cu(II) and NH3-NO3− CRFCs. Converting chemical energy in fuels and oxidants directly into electricity and achieving simultaneous detoxification of pollutants are feasible via the CRFCs. These approaches are expected to become new options for retrieving energy from pollutants.

Direct urea fuel cell (DUFC) has caused a lot of attention in recent years because of simple availability of urea as fuel and high hydrogen storage in this compound. DUFC usually uses oxygen as the oxidant and the platinum catalysts as the cathode catalyst. In our previous research, O2 even air can in situ produce H2O2 under the action of Pd catalyst. In this experiment, we developed a unique DUFC, which used H2O2 as the oxidant and Pd/C as the cathode catalyst. The results demonstrate that when H2O2 served as the oxidant, the open circuit voltage and maximum power density of DUFC are much higher than those of DUFC with O2 as the oxidant. Therefore, if O2 or air can be in situ converted to H2O2, the performance of the fuel cell can be greatly improved.

As the main greenhouse gas, CO2 is considered as a threat in the context of global warming. Many available technologies to reduce CO2 emission was about CO2 separation from coal combustion and geological sequestration. However, how to deal with the cost-effective storage of CO2 has become a new challenge. Moreover, chromium pollution, the treatment of which requires huge energy consumption, has attracted people’s widespread attention. This study is aimed to develop the sequestration of CO2 via chromium slag. A dynamic leaching experiment of chromium slag was designed to testify the ability of CO2 adsorption onto chromium slag and to release Cr(VI) for stabilization. The results showed that the accumulative amounts of Cr(VI) were ca. 2.6 mg/g released from the chromium slag after 24 h of leaching. In addition, ca. 89 mg/g CO2 was adsorbed by using pure CO2 in the experiment at 12 h. Calcite is the only carbonate species in the post-carbonated slag analyzed by powder X-ray diffraction and thermal analysis. The approach provides the feasibility of the utilization of chromium slag and sequestration of the carbon dioxide at the same time at ordinary temperatures and pressures.

To eliminate contaminants like phenol and dichromate from aqueous solutions is still a hot research interest. In contrast to a traditional method within high intensity of energy input, both dichromate and phenol were removed within self-powered process through a phenol-Cr(VI) coupled redox fuel cell reactor, which was uniquely assembled on Ni/C anode the electro-oxidation of phenol takes place to give electrons and then go through the external circuit reducing Cr(VI) to Cr(III) on the cathode. Taking an example of 0.94 g L−1 phenol in 0.2 M phosphate buffer solution (PBS) serving as the anolyte and 0.15 g L−1 Cr(VI) in 0.5 M H2SO4 serving as the catholyte, a net power density of 0.184 W m−2 at 0.61 V can be gained. A removal efficiency of 98.6% for 0.94 g L−1 phenol within 132 h and 99.8% for 0.30 g L−1 Cr(VI) within 60 h can be readily achieved in the system. This confirmed in the fed-batch mode that either the contaminants of phenol and Cr(VI) in solutions is effectively removed or the energy contained in chemicals as the form of electricity has been exactly retrieved.

In order to explore the feasibility of energy-free denitrifying N-rich wastewater, a self-powered device was uniquely assembled, in which ammonia/nitrate coupled redox fuel cell (CRFC) reactor was served as removing nitrogen and harvesting electric energy simultaneously. Ammonia is oxidized at anodic compartment and nitrate is reduced at cathodic compartment spontaneously by electrocatalysis. In 7.14 mM ammonia + 0.2 M KOH anolyte and 4.29 mM KNO3 + 0.1 M H2SO4 catholyte, the nitrate removal efficiency was 46.9% after 18 hours. Meanwhile, a maximum power density of 170 mW·m-2 was achieved when applying Pd/C cathode. When NH4Cl/nitrate and ammonia/nitrite CRFCs were tested, 26.2% N-NH4Cl and 91.4% N-NO2- were removed respectively. Nitrogen removal efficiency for real leachate at the same initial NH3-N concentration is 22.9% and nitrification of ammonia in leachate can be used as nitrate source. This work demonstrated a new way for N-rich wastewater remediation with electricity generation.

The mechanism of methylene blue (MB) oxidation initiated by hydroxyl radicals (·OH) in a gas–liquid multiphase plasma reactor was investigated. Direct current corona plasma was applied to produce ·OH. The effects of liquid solution pH and plasma-forming gas components (air, N2, He, CO2) were evaluated. The removal of MB exceeded 90 % after 3 h of treatment under an air atmosphere at neutral pH, and it was shown to be mainly through the function of ·OH. Further experiments demonstrated that ·OH was mainly produced through electron-molecule collision processes. The energy efficiency of the process was assessed to be as high as 3.8 × 10−3 mol/kWh when the removal of MB reached 95.7 %. This high value was due to the countless liquid droplets greatly increasing the contact surface area. The results using CO2 as the forming gas indicated that the carbonate in solution has a negative effect on the generation of ·OH.

Microalgae have long been recognized as having the potential to provide a better source of biofuel. In this study, Spirulina platensis was cultivated in human urine to couple wastewater treatment with biomass production. The characteristics of microalgae growth under autotrophic and mixotrophic (adding glucose or sodium acetate to the urine) conditions, wastewater nutrient removal and biomass quality were examined. After 7 days, 97% of NH4+-N, 96.5% of total phosphorus (TP) and 85–98% of urea in the urine (ca. 120-diluted) were removed by the microalgae under autotrophic culture (30 °C). The addition of organic carbon was found to greatly stimulate the microalgae growth. More important, the mixotrophic grown biomass showed an increase in the content of protein, which could be converted into biocrude oil via hydrothermal liquefaction. This study suggested that it might be possible to replace a common culture medium with human urine to produce S. platensis.

With water vapor as the radical source, hydroxyl radicals (·OH) of strong oxidation property were formed by corona discharge, which was directly detected by electron spin resonance (ESR) technology. These ·OH could efficiently degrade gaseous organic pollutants so as to reduce the toxicity of waste gas. The experimental result of toluene degradation under DC corona discharge showed that the degradation efficiency of toluene was nearly 100% in the medium of air containing saturated water vapor under the condition that interelectrode voltage was 20 kV, discharge current was 0.1 mA, reaction time was 120 s and initial concentration of toluene was 168 mg/m3, respetively. Seven intermediate products of toluene oxidation dissolving in liquid phase were also determined. The empolyment of environmental friendly ·OH provides a new approach for the removal of gas pollutants.

Culture of Arthrospira platensis (Spirulina platensis) in human urine was investigated to get valuable biomass. NO3-N was the proper N source, in comparison with other N source, including urea, NH4-N and NO2-N. As a result, aerobic nitrification of human urine was performed, with above 93.6% nitrification percentage finally achieved with total-N (TN) load of 46.52 mg/(L·d), in which Arthrospira platensis was successfully grown. The main compositions of the obtained biomass are close to those in Zarrouk medium. Thus, it is possible to culture Arthrospira platensis in nitrified human urine for food production within bioregenerative life support systems (BLSSs).

A novel process combining electrocatalysis and activated carbon (AC) in fluidization mode was presented for p-nitrophenol (PNP) abatement. The synergetic effect was found by comparing with the individual electrocatalysis and AC adsorption, and the synergetic factor (f) was calculated to be 139%. Such a one-step process could almost completely remove the PNP of initial concentration of 150 mg L−1 in no more than 30 min. The mechanism of synergetic effects was due to the formation of AC microelectrodes under the electric field. Activated carbon microelectrodes in fluidization mode could largely improve the PNP degradation adsorbed on the surface of AC. Activated carbon played the double role of adsorbent and catalyst. Furthermore, AC adsorption capacity could be partly regenerated during the electrocatalysis. Sparged with O2, the removal rate of PNP was almost enhanced to 150%, compared with N2 sparged at 10-min degradation. Activated carbon amount, liquid flow rate, current, run batches, initial PNP concentration, and sparged gas were investigated to find out the factors affecting PNP abatement. The combined process showed potential application for environmental remediation.

Electro-assisted advanced process was developed for wastewater treatment of phenolic compounds. A series of correlative experiments were carried out: the degradation of phenol by the advanced electrochemical oxidation process, the degradation of chlorophenol by the photo-electrocatalysis, and the degradation of chlorophenol by pair electrodes. It was found that phenol and chlorophenol could be removed rapidly and effectively at initial concentration of 100–400 mg L−1, current density of 3.2–27.5 mA cm−2, and applied voltage of 2–5 V. The combination of electrocatalytic and UV radiation greatly accelerated the removal efficiency. The dechlorination of chlorophenol could be achieved under cathodic reduction so that it could be further oxidized more quickly and completely. The mechanism of dechlorination was proposed to be the indirect dechlorination by atomic hydrogen. The electro-assisted advanced processes were suitable for the treatment of the phenolic compounds.
