Inside Back Cover: Boosting Photocatalytic Water Oxidation Over Bifunctional Rh0‐Rh3+ Sites (Angew. Chem. Int. Ed. 42/2021)

Abstract

Bifunctional Rh0–Rh3+ sites anchored on Mo-doped BiVO4 show a high visible-light photocatalytic oxygen production activity, as reported by Peng Fei Liu, Zheng Jiang, Hua Gui Yang, and co-workers in their Research Article on page 22761. Operando XAFS results and DFT calculations illustrate the bifunctional OER mechanism on the Rh0–Rh3+ sites: the oxygen intermediate attacks the Rh3+ sites, facilitating a hydrogen atom transfer to the adjacent Rh0 sites, which synergistically optimizes the OER energetics.
