Cerium Oxide‐Induced Synchronous Lattice Oxygen Activation and Accelerated Deprotonation Kinetics in Cobalt (oxy)Hydroxide for Robust Water Oxidation

, and coupling with commercial Pt/C in anion exchange membrane water electrolyze (AEMWE) to realize energy-saving hydrogen production. This work is instructive for the design of high-performance OER catalysts through controlling the electron orbitals hybridization state of the catalysts to synchronously accelerate the kinetics of each link in OER.
