Abstract

Read online

Perovskite oxides are attractive candidates as catalysts for water electrolysis however their rational design is rare. Here, the authors report a series of cobaltite perovskites where the covalency of the Co-O bond and concentration of oxygen vacancies are controlled, and assess their catalytic performance.
