Oxygen reduction electrocatalysis: From conventional to single-atomic platinum-based catalysts for proton

Frontiers in Energy doi: 10.1007/s11708-023-0907-3

Abstract: Platinum (Pt)-based materials are still the most efficient and practical catalysts to drive the sluggish, Pt single-atom catalysts (Pt SACs) as the recently burgeoning hot materials with a potential to achieveThe single-atomic Pt coordinating with non-metals and alloying with metals as well as the metal-supportinteractions of Pt single-atoms with carbon/non-carbon supports are emphasized in terms of the ORR activityand stability of the catalysts.
