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.
