Hydrogen peroxide (H2O2), renowned for its green and environmentally friendly properties, has catalyzed extensive research efforts aimed at developing synthetic methods, largely fueled by its diverse industrial applications, including textile bleaching , chemical synthesis 2 , papermaking , pharmaceuticals , and water purification . Currently, industrial H2O2 production primarily depends on the costly and polluting Riedl-Pfleiderer process, involving alkyl anthraquinone oxidation and hydrogenation. Fortunately, the direct electrosynthesis of H2O2 from H2 and O2 through the two-electron oxygen reduction reaction (2e -ORR) presents a promising alternative. This strategy offers lower energy consumption, environmental friendliness, and reduced transportation and storage risks, making it suitable for small-scale and even in situ production. Despite larger development (e.g. noble-metal, metal oxide, carbon material and so on) regarding the rational design of electrocatalysts for 2e -ORR, however, available electrocatalysts for 2e -ORR suffer from limited activity and selectivity, hindering widespread commercial adoption. Thus, finding a highperformance electrocatalyst for 2e -ORR is crucial as an alternative to the Riedl-Pfleiderer method.
