As a potential adsorbent material, loose, porous livestock manure biochar provides a new approach to livestock manure resource utilization. In this study, coconut husks (CH) and livestock manure, i.e., cow dung (CD), pig manure (PM), and chicken manure (CM) were used as biomass precursors for preparation of biochar via high-temperature pyrolysis and CO2 activation. Characterization technologies, such as scanning electron microscopy, Fourier transform infrared spectroscopy, adsorption–desorption isotherms, and pore size distributions, were used to study the microscopic morphologies and physicochemical properties of unactivated and activated biochar materials. The results showed that CD biochar provides better adsorption performance (up to 29.81 mg H2S/g) than CM or PM biochar. After activation at 650° for 1 h, the best adsorption performance was 38.23 mg H2S/g. For comparison, the CH biochar removal performance was 30.44 mg H2S/g. Its best performance was 38.73 mg H2S/g after 1 h of activation at 750 °C. Its best removal performance is equivalent to that of CH biochar activated at a temperature that is 100 °C higher. Further material characterization indicates that the H2S removal performance of livestock-manure–derived biochar is not entirely dependent on the specific surface area, but is closely related to the pore size distribution.

One two-dimensional Fe-based metal–organic framework (FeSC1) and one one-dimensional coordination polymer (FeSC2) have been solvothermally prepared through the reaction among FeSO4·7H2O, the tripodal ligand 4,4′,4″-s-triazine-2,4,6-triyl-tribenzoate (H3TATB), and flexible secondary building blocks p/m-bis((1H-imidazole-1-yl)methyl)benzene (bib). Given that their abundant interlayer spaces and different coordination modes, two compounds have been employed as battery-type electrodes to understand how void space and different coordination modes affect their performances in three-electrode electrochemical systems. Both materials exhibit outstanding but different electrochemical performances (including distinct capacities and charge-transfer abilities) under three-electrode configurations, where the charge storage for each electrode material is mainly dominated by the diffusion-controlled section (i ∝ v0.5) through power-law equations. Additionally, the partial phase transformations to more stable FeOOH are also detected in the long-term cycling loops. After coupling with the capacitive carbon-based electrode to assemble into the semi-solid-state battery–supercapacitor-hybrid (sss-BSH) devices, the sss-FeSC1//AC BSH device delivers excellent capacitance, superior energy and power density, and longstanding endurance as well as the potential practical property.

With the rapid development of metal–organic frameworks (MOFs), a variety of MOFs and their derivatives have been synthesized and reported in recent years. Commonly, multifunctional aromatic polycarboxylic acids and nitrogen-containing ligands are employed to construct MOFs with fascinating structures. 4,4′,4′′-(1,3,5-Triazine-2,4,6-triyl)tribenzoic acid (H3TATB) and the bidentate nitrogen-containing ligand 1,3-bis[(imidazol-1-yl)methyl]benzene (bib) were selected to prepare a novel ZnII-MOF under solvothermal conditions, namely poly[[tris{μ-1,3-bis[(imidazol-1-yl)methyl]benzene}bis[μ3-4,4′,4′′-(1,3,5-triazine-2,4,6-triyl)tribenzoato]trizinc(II)] dimethylformamide disolvate trihydrate], {[Zn3(C24H12N3O6)2(C14H14N4)3]·2C3H7NO·3H2O} n (1). The structure of 1 was characterized by single-crystal X-ray diffraction, IR spectroscopy and powder X-ray diffraction. The properties of 1 were investigated by thermogravimetric and fluorescence analysis. Single-crystal X-ray diffraction shows that 1 belongs to the monoclinic space group Pc. The asymmetric unit contains three crystallographically independent ZnII centres, two 4,4′,4′′-(1,3,5-triazine-2,4,6-triyl)tribenzoate (TATB3−) anions, three complete bib ligands, one and a half free dimethylformamide molecules and three guest water molecules. Each ZnII centre is four-coordinated and displays a distorted tetrahedral coordination geometry. The ZnII centres are connected by TATB3− anions to form an angled ladder chain with large windows. Simultaneously, the bib ligands link ZnII centres to give a helical Zn–bib–Zn chain. Furthermore, adjacent ladders are bridged by Zn–bib–Zn chains to form a fascinating three-dimensional self-penetrated framework with the short Schläfli symbol 65·7·813·9·10. In addition, the luminescence properties of 1 in the solid state and the fluorescence sensing of metal ions in suspension were studied. Significantly, compound 1 shows potential application as a fluorescent sensor with sensing properties for Zr4+ and Cu2+ ions.

We have successfully synthesized two kinetically stable CuI-MOFs with 2D layered architectures by introduction of β-[Mo8O26]4− clusters, denoted as [CuI2(β-Mo8O26)(bnie)2][Cu2(bnie)2] (NAU-1) and [CuI2(bnie)2]2(β-Mo8O26) (NAU-2) respectively. According to the result of electrochemical analysis, all these framework active materials behave as pseudo-capacitor and exhibit high capacitance and excellent energy delivery efficiency. For instance, the maximum gravimetric capacitance of NAU-1 and NAU-2 electrode is 800 and 828 F g−1 at a current density of 1.0 A g−1 separately. Theory mechanism analyses suggest capacitive (i ∝ v) and diffusion-controlled (i ∝ v1/2) currents contribute equally during redox reaction process. Particularly, after integration of carbon-based conductive matrix with CuI-MOFs, the structural stability and cycling life are both promoted. Whether carbon nanotubes or graphene oxide, they both boost the conductivity of the electrode and the capacitance retentions of these electrodes keep growing trends that all surpass 100% after 5000 continuous cycles. The excellent electrochemical performance may be ascribed to the β-[Mo8O26]4− clusters occupying the void space of 2D layered structures that facilitate electron transport and ions transmission.

Synthesizing kinetically stable coordination polymers (CPs) through ligand functionalization can effectively improve their supercapacitive performances. Herein, we have successfully synthesized three novel and topological Co-CPs by variation of flexible N-donor ligand and inorganic anions, namely interpenetrated [Co(HTATB)(o-bib)]•H2O, extended 2D layered Co(HTATB)(m-bib)•2H2O and 3D Co(HTATB)(m-bib), where bib is the flexibly N-donor bis((1H-imidazol-1-yl)methyl)benzene linker (o- and m- means ortha- and metra- separately) and HTATB is the deprotonation mode from 4,4',4''-s-triazine-2,4,6-triyl-tribenzoicacid (H3TATB). The various Co-CPs have been directly applied in the field of supercapacitors. All these framework materials exhibit high capacitance, excellent energy delivery efficiency and good cycling performance. For instance, the maximum specific capacitance for penetrated 3D networks is 2572 F g-1 at 2.0 A g-1, and the mean energy delivery efficiency is up to 92.7% based on the tested current densities. Comparing 2D layered and extended 3D networks, the 3D interpenetrated and polythreaded architectures, which could provide more active sites and thus promote fast charging and discharging process. Furthermore, the Li+ uptake-release abilities for the Co-based CPs are also investigated and the initial discharge capacity value for the 3D interpenetrated structures can reach up to 1792 mAh g-1 at a current density of 50 mA g-1.
