Glycerol electrolysis affords a green and energetically favorable route for the production of value‐added chemicals at the anode and H₂ production in parallel at the cathode. Here, a facile method for trapping Pt nanoparticles at oxygen vacancies of molybdenum oxide (MoO_x) nanosheets, yielding a high‐performance MoO_x/Pt composite electrocatalyst for both the glycerol oxidation reaction (GOR) and the hydrogen evolution reaction (HER) in alkaline electrolytes, is reported. Combined electrochemical experiments and theoretical calculations reveal the important role of MoO_x nanosheets for the adsorption of glycerol molecules in GOR and the dissociation of water molecules in HER, as well as the strong electronic interaction with Pt. The MoO_x/Pt composite thus significantly enhances the specific mass activity of Pt and the kinetics for both reactions. With MoO_x/Pt electrodes serving as both cathode and anode, two‐electrode glycerol electrolysis is achieved at a cell voltage of 0.70 V to reach a current density of 10 mA cm⁻², which is 0.90 V less than that required for water electrolysis.

Electrochemical valorization of biomass waste (e.g., glycerol) for production of value‐added products (such as formic acid) in parallel with hydrogen production holds great potential for developing renewable and clean energy sources. Here, a synergistic effort between theoretical calculations at the atomic level and experiments to predict and validate a promising oxide catalyst for the glycerol oxidation reaction (GOR) are reported, providing a good example of designing novel, cost‐effective, and highly efficient electrocatalysts for producing value‐added products at the anode and high‐purity hydrogen at the cathode. The predicted CoMoO₄ catalyst is experimentally validated as a suitable catalyst for GOR and found to perform best among the investigated metal (Mn, Co, Ni) molybdate counterparts. The potential required to reach 10 mA cm⁻² is 1.105 V at 60 °C in an electrolyte of 1.0 m KOH with 0.1 m glycerol, which is 314 mV lower than for oxygen evolution. The GOR reaction pathway and mechanism based on this CoMoO₄ catalyst are revealed by high‐performance liquid chromatography and in situ Raman analysis. The coupled quantitative analysis indicates that the CoMoO₄ catalyst is highly active toward CC cleavage, thus presenting a high selectivity (92%) and Faradaic efficiency (90%) for formate production.

Carboxylated cellulose nanofibers, prepared by TEMPO-mediated oxidation (TOCN), were processed into asymmetric mesoporous membranes using a facile paper-making approach and investigated as lithium ion battery separators. Membranes made of TOCN with sodium carboxylate groups (TOCN-COO^–Na⁺) showed capacity fading after a few cycles of charging and discharging. On the other hand, its protonated counterpart (TOCN-COOH) showed highly improved electrochemical and cycling stability, displaying 94.5% of discharge capacity maintained after 100 cycles at 1 C rate of charging and discharging. The asymmetric surface porosity of the membranes must be considered when assembling a battery cell as it influences the rate capabilities of the battery. The wood-based TOCN-membranes have a good potential as an ecofriendly alternative to conventional fossil fuel-derived separators without adverse side effects.

The industrial lignin used here is a byproduct from Kraft pulp mills, extracted from black liquor. Since lignin is inexpensive, abundant and renewable, its utilization has attracted more and more attention. In this work, lignin was used for the first time as binder material for LiFePO₄ positive and graphite negative electrodes in Li-ion batteries. A procedure for pretreatment of lignin, where low-molecular fractions were removed by leaching, was necessary to obtain good battery performance. The lignin was analyzed for molecular mass distribution and thermal behavior prior to and after the pretreatment. Electrodes containing active material, conductive particles and lignin were cast on metal foils, acting as current collectors and characterized using scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS) and galvanostatic charge-discharge cycles. Good reversible capacities were obtained, 148 mAh·g⁻¹ for the positive electrode and 305 mAh·g⁻¹ for the negative electrode. Fairly good rate capabilities were found for both the positive electrode with 117 mAh·g⁻¹ and the negative electrode with 160 mAh·g⁻¹ at 1C. Low ohmic resistance also indicated good binder functionality. The results show that lignin is a promising candidate as binder material for electrodes in eco-friendly Li-ion batteries.
