Direct hydrogen peroxide (H2O2) electrosynthesis via the two-electron oxygen reduction reaction is a sustainable alternative to traditional energy-intensive anthraquinone technology. However, high-performance and scalable electrocatalysts with industrial-relevant production rates remain be challenging, partially due insufficient atomic level understanding in catalyst design. Here we utilize theoretical approaches identify transition-metal single-site catalysts for using *OOH binding energy as descriptor.

Metal-organic frameworks (MOFs) with highly adjustable structures are an emerging family of electrocatalysts in two-electron oxygen reduction reaction (2e-ORR) for H2O2 production. However, the development MOF-based 2e-ORR catalysts high selectivity and production rate remains challenging. Herein, elaborate design fine control over MOFs at both atomic nano-scale is demonstrated, enabling well-known Zn/Co bimetallic zeolite imidazole (ZnCo-ZIFs) as excellent electrocatalysts.

The integration of highly active single atoms (SAs) and atom clusters (ACs) into an electrocatalyst is critically important for high-efficiency two-electron oxygen reduction reaction (2e- ORR) to hydrogen peroxide (H2 O2 ). Here we report a tandem impregnation-pyrolysis-etching strategy fabricate the oxygen-coordinated Fe SAs ACs anchored on bacterial cellulose-derived carbon (BCC) (FeSAs/ACs-BCC). As electrocatalyst, FeSAs/ACs-BCC exhibits superior electrocatalytic activity selectivity toward 2e- ORR, affording onset potential 0.78 V (vs. RHE) high H2 96.5 % in 0.1 M KOH. In flow cell reactor, also achieves production with yield rate 12.51±0.18 mol gcat-1 h-1 faradaic efficiency 89.4 %±1.3 at 150 mA cm-2 .
