Abstract

Abstract: Development of cost‐effective and highly efficient oxygen evolution reaction (OER) electrocatalysts has become a vital project of renewable energy technologies. The OER is critical for a variety of electrochemical energy devices such as water electrolyzers, metal‐air batteries, CO2 reduction, and electrosynthesis of ammonia. Compared to extensively studied metal oxide catalysts, graphitized carbon catalysts have been newly emerged as promising OER catalysts especially in less corrosive alkaline media, due to their low cost, high electrical conductivity, unique physicochemical properties, and excellent electrocatalytic performances. In this review, we discussed recent advances in nanostructured carbon electrocatalysts. At first, metal‐free OER carbon electrocatalysts including single‐ and multi‐heteroatom doping and edge‐ and defect‐rich defects are introduced. Then, transition metal and heteroatom co‐doped nanocarbons are summarized including Co−N−C, Ni−N−C, and Fe‐N−C. In addition, carbon based hybrid electrocatalysts are highlighted, which include carbon based transition metal nitrides (TMNx ), sulfides (TMSx ), and selenides (TMSex ), and phosphides (TMPx ). Finally, current challenges and perspective for future research on carbon‐based OER catalysts are outlined. Abstract : This review focuses on recent advances in nanostructured carbon electrocatalysts for the challenging oxygen evolution reaction in alkaline media. The discussed carbon catalysts include edge‐ and defect‐rich carbon, single‐ and multi‐heteroatom dopings, transition metal co‐doped carbons, and carbon composite catalysts containing transition metal compounds such as nitrides, sulfides, selenides, and phosphides.
