摘要

Selective synthesis of hydrogen peroxide (H2O2) by two-electron oxygen reduction reaction (2e– ORR) has emerged as an attractive alternative to the complex and energy-consuming anthraquinone method. Electrocatalysts play a crucial role in this process, as they determine catalytic activity and selectivity, which are strongly related to their geometric and electronic structures. However, the complexity of the composition and structure of the catalytically active site poses a significant challenge to understanding the relationship between the geometric/electronic structures and ORR activity/selectivity of the electrocatalyst. Herein, we systematically summarize and discuss the latest advances in the geometric and electronic modulations of electrocatalysts toward H2O2 synthesis. First, the basic principle of adsorption and reduction behaviors of oxygen species on the catalyst surface is introduced, and the influence of geometric and electronic structures is highlighted. Secondly, the recent advances in catalyst design via these two strategies are presented. Thirdly, the features of various electrocatalysts associated with their electrochemical performance are summarized and analyzed. Finally, the current challenges and future directions for the research and development of H2O2 production are discussed. This review provides insights that contribute to the development of next-generation catalysts for sustainable H2O2 production, addressing both environmental and energy challenges.
