中文摘要：

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^2/ 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15mg/L,ZnIn2S4投加量0.1g/L,pH=8,光催化降解率达到97.09%.

英文摘要：

TThe 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^2/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%.
