Cover Feature: Smart Control of Composition for Double Perovskite Electrocatalysts toward Enhanced Oxygen Evolution Reaction (ChemSusChem 23/2019).

Keywords: doping; electrocatalysis; perovskites; oxygen evolution reaction; water splitting B The Cover Feature b shows how oxygen evolution reaction (OER)-active elements are simultaneously introduced into the B-site and B'-site of a B-site-ordered double perovskite (A SB 2 sb BB'O SB 6 sb ), leading to an enhancement in the exposed reactive sites and an optimum surface chemical state.
