Controlled Synthesis of Hierarchical Flower-like CuS Spheres by a Facile Microwave Hydrothermal Method
Hierarchical flower-like CuS spheres have been synthesized by a facile microwave hydrothermal method using cetyltrimethylammonium bromide (CTAB) as the surfactant.The as-prepared CuS crystallites under different CTAB contents were characterized by X-ray diffraction,field-emission scanning electron microscopy,transmission electron microscopy,and selected area electron diffraction.Results show that the CTAB-assisted CuS particles have hierarchical flower-like microstructures that were assembled by thin nanoflakes with thickness of 10~20 nm.The corresponding HRTEM images reveal that these nanoflakes are composed of many nanoparticles with average size of about 7 nm.Moreover,when increasing the CTAB contents from 0 g/mL to 0.02 g/mL,the as-prepared CuS particles were found to have better dispersion stability with decreased average size of the hierarchical flower-like spheres.Comparing with the bulk CuS particles,the related UV-vis absorption spectrum of the as-prepared crystallites exhibits an obvious red shift with the absorption peak at 739 nm.
