Preparation Of CuS And Ag - Doped CuS Composites And Their Photocatalytic Properties

With the vigorous development of the industry, water pollution becomes a big problem to threat human harmonious development. Due to the complex of industrial waste water, high sticky force characteristics of the traditional management method and can’t control the water pollution, so the development of new photocatalytic degradation of materials also has become a new research hotspot. CuS as an important kind of transition metal sulfides, due to its diverse topography, small size, large specific surface area, and control water pollution for us to provide a new research direction. In this paper, through a simple hydrothermal method and solvolent method of synthesis of a variety of CuS nanomaterials, morphology and try to adope Ag in it in order to improve its performance.The thesis is mainly divided into the following two aspects:1. The preparation of CuS nanometeials by hydrothermal methodCuS nanoparticles were synthesized by hydrothermal method using CuCl2·2H2O and TAA. CuS nanoparties can be obtained by adjusting the reactants concentration and reaction temperature. They were characteried by the SEM, XRD and IR. The photocatalytic properties of rhodamine B and methyl orange were measured.CuS nanotubes and nanoparticles were synthesized by hydrothermal method using CuCl2·2H2O and TAA as reactants, PEG400 as surfactant. CuS nanomaterials can be obtained by adjusting the desoge of PEG400 and reaction temperature. They were characteried by the SEM, XRD, FT-IR and PL. And the photocatalytic properties of rhodamine B and methyl orange were measured.2. The preparation of CuS nanometerials by solvothermal methodCuS nanometerials were synthesized by solvothermal method using copper salts and TAA. A series of CuS nanomaterials can be obtained by adjusting the kinds of copper salts, reactants concentration, reaction temperature and reaction time. They were characteried by the SEM, XRD. And the photocatalytic properties of rhodamine B and methyl orange were measured.CuS composites were prepared by solvothermal process, using the specimen synthesized with ethanol as solvent. The ratio, reactive time was discussed. The microstructure, morphology and spectra of composite materials were analyzed. The photocatalytic properties of rhodamine B and methyl orange were measured.
