Ru–Co Pair Sites Catalyst Boosts the Energetics for the Oxygen Evolution Reaction

Abstract Manipulating the coordination environment of the active center via anion modulation to reveal tailored activity and selectivity has been widely achieved, especially for carbon‐based single‐atom site catalysts (SACs). However, tuning ligand fields of the active center by single‐site metal cation regulation and identifying the effects on the resulting electronic configuration is seldom explored. Herein, we propose a single‐site Ru cation coordination strategy to engineer the electronic properties by constructing a Ru/LiCoO 2 SAC with atomically dispersed Ru−Co pair sites. Benefitting from the strong electronic coupling between Ru and Co sites, the catalyst possesses an enhanced electrical conductivity…
