MIL-53(Fe)的合成及其催化还原对硝基苯酚的研究

Research on synthesis and catalytic reduction of p-nitrophenol of MIL-53(Fe)

利用溶剂热合成法制备金属有机骨架材料MIL-53(Fe)。通过X射线衍射仪(XRD)、电子扫描电镜(SEM)、傅立叶变换红外光谱仪(FTIR)表征手段对材料的晶相结构及组成成分进行分析。常温常压下,通过催化还原对硝基苯酚的反应考察MIL-53(Fe)的催化活性。结果表明,MIL-53(Fe)的催化活性良好,5min对硝基苯酚的转化率达到96.8%。

In this paper,MIL-53（Fe） was prepared by sol thermal method.The structure and composi tion of sample was characterized by means of X ray diffraction （XRD）, scanning electron microscopy （SEM）, Fourier transformation infrared spectrometer （FTIR）.Catalytic activity of sample was investi gated by catalytic reduction of p nitrophenol at ambient temperature and pressure.The results showed that MIL- 53 （Fe）existed good catalytic performance and the conversion of p nitrophenol reached 96.8% in five minutes.
