摘要:
采用水热法制备可见光催化剂ZnIn2S4,利用X射线光电子能谱仪(XPS)、X射线衍射仪(XRD)、比表面积及孔径分析仪(BET)、紫外可见近红外光谱仪(UV-Vis)对所制备的催化剂的元素组成、晶体结构、比表面积及带隙能量进行了表征。以罗丹明B(RhB)为目标降解物,考察了RhB浓度、ZnIn2S4投加量以及pH对ZnIn2S4可见光催化降解RhB效果的影响。结果表明,制备得到的ZnIn2S4是平均比表面积为79.033 m?/g的六方相型微球,带隙能为2.046 eV。ZnIn2S4可见光催化降解RhB的最佳条件为RhB浓度15 mg/L,ZnIn2S4投加量0.1 g/L,pH=8,光催化降解率达到97.09%。
Abstract:
The sample of ZnIn2S4 is synthesized by hydrothermal method and characterized by XPS、XRD、BET、UV-vis. A series of experiments about the effects of operational parameters such as initial concentration of RhB , photocatalysts concentration and pH on photocatalytic degradation of RhB were carried out. The results showed that ZnIn2S4 is hexagonal microspheres with specific surface area of 79.033 m?/g and band gap is 2.046 eV. The optimum condition is as follows: the concentration of ZnIn2S4 and RhB is 0.1 g/L and 15 mg/L ,pH is 8,respectively. The degradation rate of RhB reached 97.09%
