Understanding the preparative chemistry of atomically dispersed nickel catalysts for achieving high-efficiency H₂O₂ electrosynthesis.

ABSTRACT: Electrochemical hydrogen peroxide (H₂O₂) production via two-electron oxygen reduction reaction (2e^- ORR) has received increasing attention as it enables clean, sustainable, and on-site H₂O₂ production. Mimicking the active site structure of H₂O₂ production enzymes, such as nickel superoxide dismutase, is the most intuitive way to design efficient 2e^- ORR electrocatalysts. However, Ni-based catalysts have thus far shown relatively low 2e^- ORR activity. In this work, we present the design of high-performing, atomically dispersed Ni-based catalysts (Ni ADCs) for H₂O₂ production through understanding the formation chemistry of the Ni-based active sites.
