Unified Mechanistic Insights into Hydrogen Evolution and Oxidation from Homogeneous to Heterogeneous Molecular Electrocatalysis

Direct comparisons between homogeneous and heterogeneous electrocatalysis using the same molecular system remain rare, despite their importance for catalyst design and device integration. Here, we investigate the heterogenization of the DuBois-Shaw nickel catalyst [Ni(PCy 2NArg 2)2]2+ (NiCyArg), a w
