Progress and Opportunities in Photocatalytic, Electrocatalytic, and Photoelectrocatalytic Production of Hydrogen Peroxide Coupled with Biomass Valorization

Abstract

Hydrogen peroxide (H2O2) has been considered an energy carrier (fuel) and oxidizer for various chemical synthesis and environmental remediation processes. Biomass valorization can generate high‐value‐added products in a green and pollution‐free way to solve the energy and environmental crisis. The biomass valorization coupled with H2O2 generation via photo‐, electro‐, and photoelectrocatalysis plays a positive role in sustainable targets, which can maximize energy utilization and realize the production of value‐added products and fuel synthesis. Recently, catalyst design and mechanism studies in H2O2 generation coupled with biomass valorization are in the infancy stage. Herein, this review begins with a background on photo‐, electro‐, and photoelectrocatalytic techniques for H2O2 generation, biomass valorization, and the H2O2 generation couples with biomass valorization. Meanwhile, the progress and reaction mechanism are reviewed. Finally, the prospects and challenges of a synergistic coupled system of H2O2 synthesis and value‐added biomass in achieving high conversion, selectivity, and reaction efficiency are envisioned.
