Hydrogen peroxide production via electrocatalytic two-electron oxygen reduction is an effective alternative to traditional centralized anthraquinone processes. However, this process depends on a catalyst with low cost, high activity and high selectivity. In recent years, SACs have been considered as potential catalysts for oxygen reduction and hydrogen peroxide production due to their nearly 100% atom utilization efficiency, tunable electronic structure, and excellent catalytic performance, but the regulation of SAC activity remains a challenge. Starting from the mechanism of the ORR, the influence of the binding strength of the active metal center and *OOH on the oxygen reduction reaction pathway is elucidated. This study systematically illustrates the effect of adjusting the structure of the SAC on the binding of the metal center to *OOH from three aspects: metal center atom, coordination atom and the surrounding environment of the active center, and reveals the activity and selectivity of H2O2 production.

Key words: electrocatalysis, oxygen reduction reaction, hydrogen peroxide, activity, selectivity, single-atom catalyst, *OOH intermediate, structure regulation
