摘　　要：采用水热法制备得到颗粒状MIL-101(Cr)-NH_(2),随后用油浴法将ZnIn_(2)S4纳米片原位生长均匀分散在MIL-101(Cr)-NH^(2)表面,成功制得ZnIn_(2)S4/MIL-101(Cr)-NH_(2)光催化材料。通过X射线衍射(XRD),扫描电镜(SEM),固体紫外-可见漫反射光谱(UV-Vis DRS)和傅立叶红外光谱(FT-IR)等手段对所合成的复合材料进行表征。结果显示:可见光照射180 min后,ZnIn_(2)S_(4)/MIL-101(Cr)-NH_(2)-9对罗丹明B(RhB)的去除率最高达到了99%,且经过4次循环后仍可以保持较高的降解活性。The granular MIL-101(Cr)-NH_(2)was prepared by hydrothermal method,and then the ZnIn_(2)S_(4)nanosheets were grown uniformly and dispersed on the surface of MIL-101(Cr)-NH_(2)by the oil bath method to obtain ZnIn_(2)S_(4)/MIL-101(Cr)-NH_(2)composites.The synthesized composites were characterized by XRD,SEM,UV-Vis DRS,FT-IR and other characterizations.The results showed that the degradation rate of RhB by ZIS/MIL-101(Cr)-NH2-9 was up to 99%under the visible-light irradiation within 180 minutes,and the photocatalyst maintained high degradation activity after four cycles.
