Promoting photocatalytic multiple-electron reduction in aerobic solutions using Au-tipped CdSe nanorod clusters.

Clusters of Au-tipped CdSe nanorods have been synthesized through nanorod polymerization driven by the controlled welding of the Au tips. The efficient collection of energetic electrons in the Au nanoparticles leads to a significant enhancement in catalysing multiple-electron reduction reactions by using methylene blue as the redox indicator.
