Fe-BTC担载贵金属的简单室温合成及催化性能研究
首发时间:2018-11-21
摘要:在室温下采用简单的一锅法成功合成了铁基金属有机骨架材料Fe-BTC-Pt(x w%)(x代表不同负载量,x=0,0.06,0.12,0.19,0.41,0.6,1.09)。为了理解其组成和形貌,系统地分析了合成后的材料。发现通过此方法可以获得Pt在载体Fe-BTC上纳米级别的分散。此外,基于所得Fe-BTC-Pt(x w%),通过测试其对对硝基苯酚的催化研究了其催化加氢性能。实验发现在本实验负载Pt量范围内,不同担载量下,催化性能在担载量为0.41 w%时最优。

Simple room temperature synthesis and catalytic performance of Fe-BTC supported noble matal Pt
Abstract:The iron-based metal organic frameworks Fe-BTC-Pt (x w%)(x represents different loading,x=0,0.06,0.12,0.19,0.41,0.6,1.09) supporting noble metalPt nanoparticles (NPs) were successfully synthesized at room temperature by a simple one-pot method. In order to understand their compositions and morphologies, the synthesized materials were systematically analyzed. It was found that the nanoscaled dispersion of Pt on the carrier Fe-BTC can be achieved by this method. Furthermore, all the obtained Fe-BTC-Pt (x w%)were investigated by testing their catalytic hydrogenation performance for p-nitrophenol. It was found that the catalytic performance was optimal at a loading of 0.41 w%within the range of experimental conditions.
