摘要：

With the merits of green, effective, safe and on site, hydrogen peroxide production via electrocatalytic two-electron oxygen reduction process is considered as an alternative to the traditional high pollution and energy intensive anthraquinone method. Benefitting from the virtues of high atom utilization, homogeneous active sites and high activity, single atom catalysts for two-electron oxygen reduction show great potential in hydrogen peroxide production. This paper focuses on the progress of single atom catalysts including both noble metal and non-precious metal in electrocatalytic oxygen reduction to hydrogen peroxide. Both experimental results and theoretical calculations are emphasized to reveal the relations between electronic structure and catalytic performance. Strategies to enhance the two-electron catalytic performance including altering of central metal atoms, regulation of coordinated atoms and local environment are also summarized. This paper aims to provide ideas and reference for the design of catalysts with high activity and selectivity towards hydrogen peroxide production. Opportunities and challenges of single atom catalysts for electrocatalytic oxygen reduction to hydrogen peroxide are prospected. Characterization of active sites, stability and preparation method for single atom catalysts are urgently needed to be improved to promote their development in hydrogen peroxide production via electrocatalytic oxygen reduction. © 2023 Chemical Industry Press.
