摘要

过氧化氢(H2O2)是一种广泛使用的强氧化剂,其传统的制备方法--蒽醌法和直接合成法--存在许多缺点。通过双电子氧还原反应(2e- ORR)制备 H2O2 的方法因其高效、节能、环保而被认为是传统蒽醌法的替代策略,但它仍然是一个巨大的挑战。在这篇综述中,我们阐述了 ORR 的机理和电催化性能测试的原理,总结了产生 H2O2 的电催化剂的标准性能评估技术。其次,根据理论计算和实验结果,介绍了几种高效电催化剂。结论是贵金属基材料、碳基材料、非贵金属复合材料和单原子催化剂是 2e- ORR 制备 H2O2 的首选催化剂材料。最后,总结了 2e- ORR 与传统 H2O2 生产方法相比的优势和新颖性,以及上述高效催化剂的优缺点。展望了 2e- ORR 产 H2O2 高效催化剂的应用前景和发展方向,对提高 H2O2 电化学产率和发展绿色化工生产具有重要意义。

Electrocatalysts for the Formation of Hydrogen Peroxide by Oxygen Reduction Reaction.

Hydrogen peroxide (H2O2) is a widely used strong oxidant, and its traditional preparation methods, anthraquinone method, and direct synthesis method, have many drawbacks. The method of producing H2O2 by two-electron oxygen reduction reaction (2e- ORR) is considered an alternative strategy for the traditional anthraquinone method due to its high efficiency, energy saving, and environmental friendliness, but it remains a big challenge. In this review, we have described the mechanism of ORR and the principle of electrocatalytic performance testing, and have summarized the standard performance evaluation techniques for electrocatalysts to produce H2O2. Secondly, according to the theoretical calculation and experimental results, several kinds of efficient electrocatalysts are introduced. It is concluded that noble metal-based materials, carbon-based materials, non-noble metal composites, and single-atom catalysts are the preferred catalyst materials for the preparation of H2O2 by 2e- ORR. Finally, the advantages and novelty of 2e- ORR compared with traditional methods for H2O2 production, as well as the advantages and disadvantages of the above-mentioned high-efficiency catalysts, are summarized. The application prospect and development direction of high-efficiency catalysts for H2O2 production by 2e- ORR has been prospected, which is of great significance for promoting the electrochemical yield of H2O2 and developing green chemical production.
