摘要
以氢型层状锰氧化合物为前驱体,利用预膨润的方法将正辛胺插入到锰氧层间,将其在正硅酸乙酯和异丙醇钛的混合溶剂中进行溶剂热处理,同时加入乙醇作为反应介质,成功地制得了SiO2/TiO2柱撑的层状氧化锰复合材料。应用X射线衍射(XRD),红外光谱(IR),环境扫描电镜(SEM)对该材料进行了表征。结果表明该材料具有较大的层间距(1.38nm)和较高的热稳定性(>300°C)。
A SiO2-TiO2 pillared layered manganese oxide nanohybrid was successfully synthesized by preliminarily expanding the interlayer of H-type layered manganese oxide using octylamine, followed by titanate and silicate pillaring in a mixture solution of titanium isopropoxide and tetraethylorthosilicate. At the same time, the ethanol was added in as reactive medium. The structural evolution of SiO2-TiO2 pillared layered manganese oxide nanohybrid was characterized by XRD, SEM, IR. Si02-TiO2 pillared layered manganese oxide nanohybrid had a galley height of about 1.38nm between layers and relative higher thermal stability （〉300℃）.
