摘要
采用氯化镉和硫脲为原料,在乙二胺氟硼酸盐离子液水溶液中水热法合成了树枝状硫化镉,所得产物经X射线衍射﹑扫描电镜﹑荧光光谱技术进行表征,并对枝状硫化镉光催化降解甲基橙的能力进行测试。结果表明,离子液和反应时间在枝状结构的形成中起重要作用,探讨了其形成机理。光催化性能的测试结果表明,枝状硫化镉在紫外光的照射下对甲基橙具有较高的光催化降解率,经过280min,甲基橙的降解率可以达到85%。
Dendritic cadmium sulfide were synthesized in aqueous solution of Ethylenediamine fluobo- rate-based ionic liquid（[H2NCH2CH2NH3 ]BF4） with cadmium chloride and thiourea as raw materials. The obtained products were characterized by X-ray diffraction, scanning electron microscopy, flu- orescence spectroscopy. Optical properties of dendrites CdS and photocatalytic degradation of methyl orange were tested. The results show that the ionic liquid and reaction time play an important role in the formation of dendritic structures of cadmium sulfide. A possible growth mechanism on the formation of dendritic CdS was proposed. The experiment results of photocatalysis indicate that the asprepared CdS nanostructures have high photocatalytic degradation rate for methyl orange under UV, and the photocatalytic degradation rate of methyl orange is up to 85% after 280 min degradation.
