Characterization of copper sulfide nanostructured spheres and nanotubes synthesized by microwave-assisted solvothermal method

Copper sulfide nanostructured spheres and nanotubes were successfully synthesized, using a microwave-assisted solvothermal method, by the decomposition of [Cu(CH3CSNH2)2]Cl2 complexes, formed by the reaction of CuCl2·2H2O and CH3CSNH2 in ethylene glycol at different pH values, and identified by CHNS...
