Abstract:<\/h4>\n
Developing efficient and stable earth-abundant electrocatalysts for acidic oxygen evolution reaction is the bottleneck for water splitting using proton exchange membrane electrolyzers. Here, we show that nanocrystalline CeO2<\/sub> in a Co3<\/sub>O4<\/sub>\/CeO2<\/sub> nanocomposite can modify the redox properties of Co3<\/sub>O4<\/sub> and enhances its intrinsic oxygen evolution reaction activity, and combine electrochemical and structural characterizations including kinetic isotope effect, pH- and temperature-dependence, in situ Raman and ex situ X-ray absorption spectroscopy analyses to understand the origin. The local bonding environment of Co3<\/sub>O4<\/sub> can be modified after the introduction of nanocrystalline CeO2<\/sub>, which allows the CoIII<\/sup> species to be easily oxidized into catalytically active CoIV<\/sup> species, bypassing the potential-determining surface reconstruction process. Co3<\/sub>O4<\/sub>\/CeO2<\/sub> displays a comparable stability to Co3<\/sub>O4<\/sub> thus breaks the activity\/stability tradeoff. This work not only establishes an efficient earth-abundant catalysts for acidic oxygen evolution reaction, but also provides strategies for designing more active catalysts for other reactions.<\/p>\n","protected":false},"excerpt":{"rendered":"DOI: 10.1038\/s41467-021-23390-8 Authors: Jinzhen Huang, Hongyuan Sheng, R.
