Enhancement of ZnO@RuO₂ bifunctional photo-electro catalytic activity toward water splitting.

ABSTRACT: Catalytic materials are the greatest challenge for the commercial application of water electrolysis (WEs) and fuel cells (FCs) as clean energy technologies. There is a need to find an alternative to expensive and unavailable platinum group metal (PGM) catalysts. This study aimed to reduce the cost of PGM materials by replacing Ru with RuO₂ and lowering the amount of RuO₂ by adding abundant and multifunctional ZnO. A ZnO@RuO₂ composite in a 10:1 molar ratio was synthesized by microwave processing of a precipitate as a green, low-cost, and fast method, and then annealed at 300°C and 600°C to improve the catalytic properties. The physicochemical properties of the ZnO@RuO₂ composites were investigated by X-ray powder diffraction (XRD), Raman and Four
