The novel and economical way to synthesize CuS nanomaterial of different morphologies by aqueous medium employing microwaves irradiation

Abstract

CuS nano/submicro materials with different morphologies were synthesized with spherical, tubular, leaf-like and strip type structures in a simple aqueous system under microwave irradiation and sunlight and employing Cu (CH3COO)2, CuSO4·5H2O, CuCl2, and as copper source and H2NCSNH2, Na2S2O3·5H2O and CH3CSNH2 as sulfur sources. The starting materials were used without assistance of any surfactant or template. An X-ray powder diffraction pattern confirms that the product was CuS with hexagonal phase. Scanning electron microscopy was used to observe the morphologies of the product. Different Phase transitions in CuS with respect to temperature are studied by DSC/TGA. The dependence of morphologies of product on different experimental conditions was also discussed.
