Hydrogen peroxide (HO) is a versatile and zero-emission material that is widely used in the industrial, domestic, and healthcare sectors. It is clear that it plays a critical role in advancing environmental sustainability, acting as a green energy source, and protecting human health. Conventional production techniques focused on anthraquinone oxidation, however, electrocatalytic synthesis has arisen as a means of utilizing renewable energy sources in conjunction with available resources like oxygen and water. These strides represent a substantial change toward more environmentally and energy-friendly HO manufacturing techniques that are in line with current environmental and energy goals. This work reviews recent advances in two-electron water oxidation reaction (2e-WOR) electrocatalysts, including design principles and reaction mechanisms, examines catalyst design alternatives and experimental characterization techniques, proposes standardized assessment criteria, investigates the impact of the interfacial milieu on the reaction, and discusses the value of in situ characterization and molecular dynamics simulations as a supplement to traditional experimental techniques and theoretical simulations. The review also emphasizes the importance of device design, interface, and surface engineering in improving the production of HO. Through adjustments to the chemical microenvironment, catalysts can demonstrate improved performance, opening the door for commercial applications that are scalable through tandem cell development.
过氧化氢（HO）是一种用途广泛且零排放的材料，在工业、家庭和医疗保健领域都有广泛应用。很明显，它在推进环境可持续性、作为绿色能源以及保护人类健康方面发挥着关键作用。然而，传统的生产技术侧重于蒽醌氧化，而电催化合成已成为一种结合氧气和水等可用资源利用可再生能源的方法。这些进展代表了朝着更环保、更节能的HO制造技术迈出的重大转变，符合当前的环境和能源目标。本文综述了双电子水氧化反应（2e-WOR）电催化剂的最新进展，包括设计原理和反应机制，研究了催化剂设计方案和实验表征技术，提出了标准化评估标准，研究了界面环境对反应的影响，并讨论了原位表征和分子动力学模拟作为传统实验技术和理论模拟补充的价值。综述还强调了器件设计、界面和表面工程在提高HO产量方面的重要性。通过调整化学微环境，催化剂可以表现出更好的性能，为通过串联电池开发实现可扩展的商业应用打开了大门。
