Bismuth iron molybdenum oxide solid solution: a novel and durable electrocatalyst for overall water splitting

Abstract

The drive for finding active bifunctional electrocatalysts for efficient overall water splitting continues in order to extract energy in the form of hydrogen as a clean fuel. Bismuth iron molybdenum oxide solid solution, composed of orthorhombic Bi₂MoO₆ as the major component and monoclinic Bi₃(FeO₄)(MoO₄)₂ as the minor component, has been identified as a potential electrocatalyst for the first time.
