Abstract
Abstract Hydrogen peroxide (H 2 O 2 ) 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 H 2 O 2 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 H 2 O 2 generation coupled with biomass valorization are in the infancy stage. Herein, this review begins with a background on photo‐, electro‐, and photoelectrocatalytic techniques for H 2 O 2 generation, biomass valorization, and the H 2 O 2 generation couples with biomass valorization. Meanwhile, the progress and reaction mechanism are reviewed. Finally, the prospects and challenges of a synergistic coupled system of H 2 O 2 synthesis and value‐added biomass in achieving high conversion, selectivity, and reaction efficiency are envisioned.
