Photocatalysis: Electrostatically Assembled CdS-Co₃O₄Nanostructures for Photo-assisted Water Oxidation and Photocatalytic Reduction of Dye Molecules (Small 6/2015)

Electrostatic assembly is used by O. Yehezkeli, D. R. B. de Oliveira, and J. N. Cha to couple CdS nanorods with Co3O4 nanoparticles into photocatalytic systems that simultaneously oxidize water and mediate electron transfer. On page 668, layered films of CdS nanorods and Co3O4 nanoparticles are first used to generate high photocurrents electrochemically as opposed to CdS or Co3O4 alone. Dispersed clusters of CdS nanorods conjugated with Co3O4 nanoparticles are next shown to efficiently oxidize water and reduce methylene blue in solution.
