We report a new family of earth abundant electrocatalysts for the oxygen evolution reaction (OER) discovered via high throughput screening of 1771 discrete metal oxide compositions covering the nickel-lanthanum-cobalt-cerium composition space. The catalytic performance of each of these compositions was measured under conditions applicable to distributed solar fuels generation using a three-electrode scanning drop electrochemical cell. These high throughput measurements show enhanced activity for catalyst compositions containing 20-65 metal atom % Ce. The catalytic activity and stability of a representative highly active composition (Ni0.1La0.1Co0.3Ce0.5)Ox was verified by standard rotating disc electrochemistry. Catalysts of this composition showed stable operational performance at 10 mA cm-2 for 2 h and survived a 100 h endurance test in a testbed electrolyzer.
