A Facile Design for Water-Oxidation Molecular Catalysts Precise Assembling on Photoanodes.

ABSTRACT: Regulating the interfacial charge transfer behavior between cocatalysts and semiconductors remains a critical challenge for attaining efficient photoelectrochemical water oxidation reactions. Herein, using bismuth vanadate (BiVO₄ ) photoanode as a model, it introduces an Au binding bridge as holes transfer channels onto the surfaces of BiVO₄ , and the cyano-functionalized cobalt cubane (Co₄ O₄ ) molecules are preferentially immobilized on the Au bridge due to the strong adsorption of cyano groups with Au nanoparticles. This orchestrated arrangement facilitates the seamless transfer of photogenerated holes from BiVO₄ to Co₄ O₄ molecules, forming an orderly charge transfer pathway connecting the light-absorbing laye
