摘要
利用材料自身多孔性及比表面积大的特点,本文采用溶剂热方法合成一种典型金属有机骨架材料(MOFs),MIL-68(Fe)。为进一步改善MIL-68(Fe)的催化效果,采用硼氢化钠还原法合成Ag@MIL-68(Fe)(记作Ag@MFe)复合光催化剂。并通过XRD、FTIR等分析手段对其结构和光电性能进行测试。首次利用Ag@MFe实现可见光驱动还原重金属Cr(Ⅵ)并且表现出优异的光催化性能,其中Ag负载量为1.5%时活性最佳。
Using the characteristic of porous and specific surface area,a typical metallic organic matrix material(MOFs),MIL-68(Fe)was synthesized by solvent thermal method.In order to further improve the catalytic effect of MIL-68(Fe),the synthesis of MIL-68(Fe)by sodium borohydride reduction method to obtain the Ag@MIL-68(Fe)(Ag@MFe)photocatalyst.By means of XRD and FTIR,the structure of the structures were analyzed.Cr(Ⅵ)solution was selected as the probe reaction,and the visible photocatalytic performance of Ag@MFe photocatalyst was investigated,and the 1.5%Ag@MFe showed the best photocatalytic performance.
