生物质有机物的电化学氧化具有环境友好、反应条件温和、转化率和选择性高、产氢效率高等优点，并与阴极析氢反应(HER)相结合，近年来引起了人们的广泛关注。生物质电氧化反应规模化应用的关键在于合理构建高效催化剂，以及构建的催化剂的结构优化和性能提高。本文概述了BeOR的作用机理，并对目前流行的非贵金属电催化剂进行了综述。在此基础上，系统地讨论了结构组成与催化活性的关系。此外，还总结和强调了除了杂原子掺杂、缺陷工程和异质结结构外，通过调节电子结构来开发有效催化剂的协议。最后，总结了目前构建高效BeOR催化剂研究的局限性，提出了需要深入研究的方法和思路，并讨论了BeOR研究的目标和未来的发展趋势。这有望为生物质电化学提质的规模化应用提供指导。
The electrochemical oxidation of biomass‐based organics has recently attracted attention due to its advantages of environmental friendliness, mild reaction conditions, high degree of conversion and selectivity, and high efficiency of hydrogen production coupled with the cathodic hydrogen evolution reaction (HER). The key to implementing the large‐scale application of the biomass electrooxidation reaction (BEOR) depends on the rational construction of efficient catalysts, as well as the structural optimization and performance improvement of the constructed catalysts. Herein, the mechanism of the BEOR is summarized, followed by a review of the current popular non‐noble‐metal electrocatalysts. Thereafter, the relationship between structure/composition and catalytic activity is systemically discussed. Furthermore, protocols for developing an effective catalyst by modulating the electronic structure, in addition to heteroatom doping, defect engineering, and heterojunction construction, are summarized and highlighted. Finally, the limitations of the current research on the construction of efficient BEOR catalysts are summarized, methods and ideas required for in‐depth research are proposed, and the goals and future development trends of BEOR research are discussed. This is expected to provide guidance for the large‐scale application of electrochemical biomass upgrading.
