水热法制备ZnS纳米球及其光催化性能研究

Preparation of ZnS nanos Pheres by Hydrothermal Method and its Photocatalytic Property

以醋酸锌和硫代乙酰胺为原料,采用水热法制备了ZnS纳米球.利用XRD、SEM、UV-vis和IR等分析手段对硫化锌纳米球的形貌和晶相进行了表征;并用甲基橙作为模拟污染物,考察了光催化降解性能.结果表明,硫化锌纳米球为闪锌矿结构,粒径均一,平均直径为8~40nm;在紫外光照射下对甲基橙有较好的降解作用,光催化降解1.5h,甲基橙降解率达到98%.

With zinc acetate and thioacetamide as raw material, preparation of ZnS Nanos Pheres by hydrothermal method. Using XRD, SEM, UV-vis and IR analysis of the morphology and ZnS nanospheres were characterized; and using methyl orange as simulated pollutants, photocatalytic degradation properties were studied. The results show that zinc sulfide nanoparticles as a zinc blende structure, uniform particle size, the average diameter of 8~40 nm; good effect on Methyl Orange Degradation under UV irradiation, the photocatalytic degradation of 1.5 h, degradation rate reached 98%.
