以硝酸锌和硫化氢为原料,在超重力旋转床(RPB,Rotating Packed Bed)中首次制备了球形、粒径分布较窄、分散性较好的闪锌矿纳米硫化锌粒子,平均粒径为30nm,转化率97.5％;研究了陈化时间对粒子形貌和大小的影响.并采用TEM、紫外可见光分光光度计、XRD等手段对产品的形貌、紫外吸收性能及晶相进行了表征.
By using zinc nitrate and hydrogen sulfide as source materials, nanometer zinc sulfide was synthesized by a high
gravity method in a rotating packed bed. The effect of aging time on product sizes was investigated and 48h was chosen. Well-dispersed
nanometer zinc sulfide particles with a sphalerite crystal phase were prepared. The crystal structure, optical properties, size and morphology
of the product were also characterized by XRD, UV-Vis spectrophotometer and TEM. The results show that the average particle size of ZnS obtained is about
30nm and the conversion rate is 97.5 percent.
