Abstract
Abstract Single‐atom catalysts (SACs) have been attracting extensive interest in the electrocatalytic production of hydrogen peroxide by oxygen reduction reaction (ORR). This is due to the maximal efficiency of atom utilization and intimate interaction of the metal centers with the supporting matrix that may be exploited for deliberate manipulation of the electrocatalytic activity and selectivity, in comparison with the conventional nanoparticle counterparts. Herein, we summarize recent progress of the design and engineering of SACs towards ORR for H 2 O 2 generation, based on both noble and non‐noble metals. We conclude the review with a perspective highlighting the promises and challenges involved in future research.
