Abstract: The economically viable water electrolysis technology offers great potential for the rapid development of sustainable and clean hydrogen fuel. The multiple proton-coupled electron transfer processes lead to the sluggish kinetics of the oxygen evolution reaction at the anode, which becomes the key rate-controlling step in hydrogen production by water electrolysis. Development of electrocatalysts with superior performance for biomass electrocatalytic conversion-coupled H2 generation has emerged as an attractive strategy to mitigate the OER hurdle. Herein, high-entropy phosphide nanosheets (NiFeCoWMoP) are grown on low-curvature hierarchically porous carbonized wood (CW) (NiFeCoWMoP/CW) via solvothermal and phosphide topological methods. The produced NiFeCoWMoP/CW is used as an integrated carbon electrode and presents a remarkable bifunctional properties towards both the hydrogen evolution reaction (HER) and glucose electrocatalytic conversion (GCR), delivering a high current density of 100 mA cm-2 at potentials of only -0.151 V and +1.343 V in 1 M KOH, respectively. Furthermore, the NiFeCoWMoP/CW-based electrolysis system can achieve a reaction current of 100 mA cm-2 at a low voltage of only 1.534 V for GCR coupled with H2 production. Results from this study underscore the significance of high-entropy phosphide nanosheets as multifunctional electrocatalysts for biomass electrocatalytic conversion and hydrogen production.
