Growth of Photocatalytic CdSe-Pt Nanorods and Nanonets

A hybrid Pt-CdSe nanoparticle system is prepared in aqueous media. displaying rod or nanonet structures depending on the pH. The new hybrids display morphology-dependent photocatalytic activity under visible light irradiation. Separation between photo generated charge carriers occurs at the metal/semiconductor interface (see figure), allowing redox reactions to take place at the nanoparticle surface.
