Method for preparing Cu-Zn-Sn-S nano hollow spheres

Abstract

The invention discloses a method for preparing Cu-Zn-Sn-S nano hollow spheres. The method comprises the following steps: (1) preparing a mixed water solution of cuprous chloride and thioacetamide; (2) preparing a mixed water solution of stannic chloride and thioacetamide; (3) preparing a mixed water solution of stannic chloride and thioacetamide; (4) mixing the following components by volume: 4.5-5.5 parts of the mixed solution of the step (1), 4.5-5.5 parts of the mixed solution of the step (2) and 14-16 parts of the mixed solution of the step (3), and stirring; and (5) centrifuging the reaction liquid of the step (4), and drying, thereby obtaining the product. As the process is simple, the raw materials are simple and easy to obtain, the method for preparing the Cu-Zn-Sn-S nano hollow spheres is easy for industrialization popularization; the prepared Cu-Zn-Sn-S nano hollow spheres are uniform in structure, fine in granule and wide in application prospect in fields such as solar batteries, photocatalytic hydrogen generation and lithium battery cathode materials.
