| 摘 要： | 利用一步水热合成法,在有机模板剂1,6-己二胺结构导向作用下,合成了具有MFI骨架结构的铁硅酸盐分子筛晶体Fe-Silicalite-1.并通过XRD、TG-DTA、IR和SEM等测试方法对其结构和性能进行了表征.ICP-AES及EDS分析结果表明:Fe原子进入到分子筛骨架上,质量分数约为0.66;.在以过氧化氢为氧化剂,羟化苯酚的催化反应中,苯酚的转化率为22.2;,其中65.8;为邻苯二酚,34.2;为对苯二酚.Fe-Silicalite-1分子筛晶体是一种良好的合成二酚的催化剂,具有潜在的应用价值.

| Abstract: | Fe-Silicalite-1 zeolites with MFI framework structure were synthesized using 1,6-hexamethylene-diamine as a structure direction agent via one-step hydrothermal synthesis technique. The structure and properties of as-synthesized samples were characterized by XRD,SEM,IR,TG-DTA etc. EDS and ICP-AES indicated that the transition metal iron ions were framework elements and the mass fraction was 0.66%. The catalytic activity in hydroxylation of phenol with hydrogen peroxide as the oxidant was also investigated. T... |
