The invention relates to a preparation method of a ball-shaped CdSe nanomaterial, which comprises the following steps: placing a mixed solution containing a cadmium source and a selenium source in an autoclave to react at 120° C., cooling, separating the obtained precipitate, washing and drying to obtain a wool Spherical CdSe nanomaterials. The present invention selects Na 2 SeSO 3 as the selenium source, which is the key to synthesizing hairy spherical CdSe, and at the same time studies the optimal conditions of the synthesis process. It has good application prospects for decomposing colored dyes, etc. |
