Abstract

optimises the Gibbs free energy of hydrogen adsorption by preserving moderate Mo-H binding, while excessive oxidation attenuates binding and retards the Volmer-Heyrovsky step. Thus, we identify a controllable, self-limited surface reconstruction step, rather than the metallic Mo constituent, as the key performance descriptor, guiding the design of stable carbide-based catalysts for alkaline water electrolyser technologies.
