The sulfide and heterostructures nanomaterials is important semiconductor material , it has many unique applications , such as photocatalysts , photoelectric materials . This thesis solvothermal method , successfully prepared CdS nano triangle / bismuth sulfide nanowire heterostructures homogeneous Cu1.8S , rattles shaped core-shell structure and AgBiS 2 mace -like nanostructures . The main research work as follows: 1. Cadmium nitrate , anhydrous bismuth chloride , thiourea in the thermal condition of the solvent is synthesized CdS triangle / bismuth sulfide nanowire heterostructure preliminary inquiry amount of thiourea , and the reaction temperature , reactant concentration, the impact on the product . The resulting products were using X-ray diffraction ( XRD ) , field emission scanning electron microscope ( FESEM ) , transmission electron microscopy ( TEM ) , high-resolution transmission electron microscopy ( HRTEM ) , selected area electron diffraction (SAED), photoluminescence (PL ) and the like to characterize . Studies have shown that cadmium sulfide nano triangle / bismuth sulfide nanowire heterostructures has good photocatalytic properties . Copper nitrate , thiourea as raw material , synthesized by solvothermal method a homogeneous Cu1.8S rattles shaped structure ( RTS ) , the resulting product were used SEM , transmission electron microscopy (TEM) , X -ray photoelectron spectroscopy ( XPS ) , infrared spectroscopy (IR) and other characterization. The studies show Cu1.8S RTS has a good photoelectric effect . Silver nitrate , anhydrous bismuth chloride as raw materials in the solvothermal conditions . Prepared AgBiS 2 mace -like nanostructures , the product were used XRD , SEM, TEM characterize . Preliminary study of the conditions such as temperature and concentration , and found that the concentration on the morphology of the product has an important role .
