Abstract An environmentally benign, sustainable, and cost-effective supply of H 2 O as a rapidly expanding consumption raw material is highly desired for chemical industries, medical treatment, household disinfection. The electrocatalytic production route via electrochemical oxygen reduction reaction (ORR) offers sustainable avenue the on-site from O. most crucial innovative part such technology lies in availability suitable electrocatalysts that promote two-electron (2e – ) ORR. In recent years, tremendous progress has been achieved designing efficient, robust, catalyst materials, including noble metals their alloys, metal-free carbon-based single-atom catalysts, molecular catalysts. Meanwhile, cell designs have significantly advanced applications at industrial level. This review summarizes fundamental basics advances 2e -ORR, design, mechanistic explorations, theoretical computations, experimental evaluations, designs. Perspectives on addressing remaining challenges are also presented with an emphasis large-scale synthesis route.

Abstract The electrochemical oxygen reduction reaction (ORR) and evolution (OER) are fundamental processes in a range of energy conversion devices such as fuel cells metal–air batteries. ORR OER both have significant activation barriers, which severely limit the overall performance that utilize ORR/OER. Meanwhile, is another very important involving has been widely investigated. occurs aqueous solutions via two pathways: direct 4-electron or 2-electron pathways from O 2 to water (H O) hydrogen peroxide ). Noble metal electrocatalysts often used catalyze ORR, despite fact noble certain intrinsic limitations, low storage. Thus, it urgent develop more active stable low-cost electrocatalysts, especially for severe environments (e.g., acidic media). Theoretically, an ideal electrocatalyst should provide adequate binding species. Transition metals not belonging platinum group metal-based oxides substance could give d orbital species binding. As result, transition regarded substitute typical precious electrocatalysts. However, development oxide catalysts reactions still faces challenges, e.g., catalytic activity, stability, cost, mechanism. We discuss principles underlying design catalysts, including influence crystal structure, electronic structure on their performance. also challenges associated with developing potential strategies overcome these challenges.
