Interfacial Engineering of MoO 2 ‐FeP Heterojunction for Highly Efficient Hydrogen Evolution Coupled with Biomass Electrooxidation

Abstract Simultaneous highly efficient production of hydrogen and conversion of biomass into value‐added products is meaningful but challenging. Herein, a porous nanospindle composed of carbon‐encapsulated MoO 2 ‐FeP heterojunction (MoO 2 ‐FeP@C) is proposed as a robust bifunctional electrocatalyst for hydrogen evolution reaction (HER) and biomass electrooxidation reaction (BEOR). X‐ray photoelectron spectroscopy analysis and theoretical calculations confirm the electron transfer from MoO 2 to FeP at the interfaces, where electron accumulation on FeP favors the optimization of H 2 O and H* absorption energies for HER, whereas hole accumulation on MoO 2 is responsible for improving the BEOR activity.
