Polypyrrole-Ru(2,2'-bipyridine)32+/MoSx structured composite film as a photocathode for the hydrogen evolution reaction.

The development of photoelectrochem. devices for solar light-driven water splitting and H2 prodn. requires new strategies for the fabrication of materials that combine the necessary photoredox and catalytic properties, to allow the hydrogen evolution reaction (HER) to take place at a low overvoltage under visible light irradn. We report the first example of a structured composite, synthesized by electrodeposition of MoSx cocatalyst into a photosensitive Ru complex film deposited onto carbon electrodes by electropolymn. of a pyrrole-functionalized RuII(2,2'-bipyridine)32+. Composite films show efficient photocatalytic activity for HER. Our study highlights the great simplicity of this versatile electrochem. procedure to synthesize photocathodes. [on SciFinder(R)]
