Electrostatic assembly is used here to couple CdS nanorods with Co 3 O 4 nanoparticles into photocatalytic systems that simultaneously oxidize water and mediate electron transfer. Layered films of CdS nanorods and Co 3 O 4 nanoparticles are first used to generate high photocurrents electrochemically as opposed to CdS or Co 3 O 4 alone. Dispersed clusters of CdS nanorods conjugated with Co 3 O 4 nanoparticles are next shown to efficiently oxidize water and reduce methylene blue in solution.
