Balancing Competitive Intermediate Behaviors on D‐f Hybridized Ni‐MOF‐Derived Catalysts for Alkaline Hydrogen Oxidation Reaction

ABSTRACT Although Ni‐based catalysts have been regarded as promising Pt‐free catalysts for alkaline hydrogen oxidation reaction (HOR), the competitive adsorption of H species and O‐containing species on Ni active sites significantly hinders its practical application. Metal‐organic frameworks (MOF) have emerged as highly favorable precursors for electrocatalyst synthesis due to their large specific surface area and abundant accessible active sites. Herein, a Ni‐SmO x /C catalyst is constructed by the incorporation of f‐block rare earth element (Sm) into Ni‐based MOF derivative, demonstrating its remarkable alkaline HOR behaviors on account of the well‐balanced competitive behaviors of diverse reaction…
