Ion Exchange Processed CdS Nanorods in Powder Form Using Cadmium Hydroxide Nanowires By Wet Chemical Route

Simple, inexpensive and soft chemical route (wet chemical method) was employed for the synthesis of bulk forms of cadmium hydroxide [Cd(OH)2] nanowires bundles and their conversion to cadmium sulphide [CdS] nanorods at room temperature by simple anion exchange route. Due to difference in solubility product and diffusion rates of the Cd(OH)2 and CdS, the anion exchange reaction was taken place and CdS nanorods were formed. CdS nanorods were characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) analysis. Since CdS is semi-conducting material, it has variety of potential applications, this work demonstrates a cost effective method for the synthesis of CdS nanorods in bulk form like CNT.
