The morphologies and photocatalytic activity of the CdS nanostructures are sensitively dependent on the synthesis condition. Here, CdS nanostructures with various morphologies were synthesized by controlling the amine species under different reaction conditions. Especially, one-dimensional CdS nanorods with average diameter of ¡«10 nm and length of ¡«200 nm were successfully synthesized by a facile ¡°one-pot¡± reflux method by using diethylenetriamine (DETA) as template and coordination agent. And the formation of CdS nanorods followed solvent coordination molecular template (SCMT) mechanism. By application of these materials as catalysts in photodegradation of methylene blue and photo-induced water splitting, it was found that the DETA-assisted synthesized CdS nanorods exhibit higher photocatalytic activities than the other CdS nanostructure. The favorable photocatalytic performance for the CdS nanorods should be ascribed to their anisotropic characteristic and good dispersion, leading to excellent photogenerated electron/hole separation ability.
