Electrochemical performance of CdS nanomaterials synthesized by microemulsion techniques

摘要

Precursor cadmium compounds influence the electro-catalytic performance of CdS nanomaterials for sulphide/polysulphide redox couple reaction. CdS nanorods and nanoparticles were synthesized from different raw materials, namely Cd(NO_3)_2, CdCl_2 or CdO, by a room temperature microemulsion approach using CS_2 as a sulphur source. Cadmium salts (i.e. CdCl_2, Cd(NO_3)_2) result in single phase CdS crystals with hexagonal structure while CdO gives two crystal phases with majority of cubic structure. Nanorods, produced from CdCl_2, demonstrated the best catalytic performance for the enhancement of the polysulphide reaction.
