Valorizing Lignocellulosic Waste Through Mediated Electrochemical Oxidation for Efficient, Low-Voltage Hydrogen Production
Short Introductive summary
In this work, a mediated electrochemical approach based on phosphomolybdic acid (PMA) is proposed for the valorization of lignocellulosic biomass coupled with low-voltage hydrogen generation. The complete process was demonstrated to operate at a cell potential of 0.7 V vs SHE at 25 °C. The extent of biomass oxidation and electron transfer efficiency varies depending on the substrate. Significant degradation of organic components after the oxidative pretreatment was confirmed by GC-MS (including analyses after silylation) and HPLC analyses. The electrolysis experiments were performed at 0.7 V vs SHE, corresponding to an electrical energy consumption of approximately 67 MJ/kg H?, markedly lower than conventional water electrolysis.
