Development of robust noble-metal free lanthanum, neodymium doped Li_1.05Ni_0.5Mn_1.5O₄ as a bifunctional electrocatalyst for electrochemical water splitting.

ABSTRACT: Catalysts for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) are at the heart of water oxidation reactions. Despite continuous efforts, the development of OER/HER electrocatalysts with high activity at low cost remains a big challenge. Herein, we report a composite material consisting of Li_1.05Ni_0.5Mn_1.5O₄, Li_1.05Ni_0.5 La_0.10Mn_1.40O₄, and Li_1.05Ni_0.5 Nd_0.10Mn_1.40O₄ as a bifunctional electrocatalyst for OER and HER applications. Though the catalyst has a modest activity for HER, it exhibits high OER activity thereby making it a better nonprecious electrocatalyst for both OER and HER. The catalytic activity arises fro
