通过溶剂热合成法，在不同合成条件下合成了MIL‐53（Fe），并利用X射线衍射仪（XRD）测定了样品的晶相结构，利用扫描电镜（SEM ）观察了样品的形貌及粒径大小，通过紫外可见漫反射（UV‐vis）考察了样品的紫外可见光吸收情况，并计算了样品的带隙能。研究了样品对罗丹明B光降解的催化活性。实验结果表明，不同合成条件下合成的样品对罗丹明B的光催化降解效果不同，可以通过对合成条件的调变来控制样品的光催化效果。

In this paper ,MIL‐53(Fe) was prepared by solvothermal method under different sythetic conditions .The phase structure of samples were characterized by XRD ,the morphology and particle size of samples were obtained by SEM ,the ultraviolet visible light absorption of samples were explored by UV‐vis and the band gap energy of samples were calculated from the absorption data .The photocatalytic activities of the samples on Rhodanmine B degradation were investigated .The results show different photocatalytic effects for the samples prepared under different synthetic condition .Accordingly ,photocatalytic effect of samples can be controlled through the variation of different synthetic conditions .
