摘要 以硝酸镉、硝酸铁和硫脲为原料,水为溶剂,通过水热法一步合成铁掺杂的硫化镉。产物经SEM,XRD,EDS和XPS等技术进行表征,以亚甲基蓝的光催化降解为目标反应,评价其光催化活性。结果表明:水热温度对硫化镉的形貌影响较大,不同反应温度可分别得到球状、花状、簇状和棒状的硫化镉,其中花状硫化镉的光催化性能最高。XRD分析表明,160℃反应时,所得掺铁的硫化镉均为六方晶体结构。光催化实验表明,铁掺杂能进一步提高硫化镉的催化活性,当Fe和Cd的掺杂比为1∶10时,催化效果最佳。

Abstract:Fe-doped cadmium sulfide was prepared by hydrothermal method in aqueous solution using cadmium nitrate, ferric nitrate and thiourea as raw materials. The samples were characterized by SEM, XRD, EDS and XPS. The photocatalytic degradation of methylene blue (MB) in aqueous solution was used as a target reaction to evaluate their photocatalytic activity. The experimental results show that the reaction temperature has a great effect on the morphology of cadmium sulfide, and spherical, flowerlike, clustered and rodlike cadmium sulfide are obtained in various reaction temperatures. Among them, the photocatalytic activity of flowerlike CdS is observed to be better than other CdS materials. The XRD indicates that Fe-doped cadmium sulfide is hexagonal crystal structure when the reaction temperature is 160℃. The experimental results also indicate that Fe-doped can obviously improve the photocatalytic activity of cadmium sulfide and when the doping ratio of Fe to Cd is 1:10, the photocatalytic effect is the best of all.
