Hydrogen peroxide (HO) is a crucial chemical applied in various industry sectors. However, the current industrial anthraquinone process for HO synthesis is carbon-intensive. With sunlight and renewable electricity as energy inputs, photocatalysis and electrocatalysis have great potential for green HO production from oxygen (O) and water (HO). Herein, we review the advances in pairing two-electron O reduction and two-electron HO oxidation reactions for dual-pathway HO synthesis. The basic principles, paired redox reactions, and catalytic device configurations are introduced initially. Aligning with the energy input, the latest photocatalysts, electrocatalysts, and photo-electrocatalysts for dual-pathway HO production are discussed afterward. Finally, we outlook the research opportunities in the future. This minireview aims to provide insights and guidelines for the broad community who are interested in catalyst design and innovative technology for on-site HO synthesis.
过氧化氢（H₂O₂）是一种应用于各个工业领域的关键化学品。然而，当前用于合成H₂O₂的工业蒽醌法是碳密集型的。以阳光和可再生电力作为能量输入，光催化和电催化在利用氧气（O₂）和水（H₂O）绿色生产H₂O₂方面具有巨大潜力。在此，我们综述了用于双途径H₂O₂合成的双电子氧还原和双电子过氧化氢氧化反应的进展。首先介绍了基本原理、成对的氧化还原反应和催化装置配置。随后，结合能量输入，讨论了用于双途径H₂O₂生产的最新光催化剂、电催化剂和光电催化剂。最后，我们展望了未来的研究机会。本综述旨在为对现场H₂O₂合成的催化剂设计和创新技术感兴趣的广大群体提供见解和指导。
