高温水热合成具有高稳定性的有序介孔材料

Hydrothermal Synthesis of Ordered Mesoporous Materials with High Stability at High Temperatures

高温水热合成路线作为合成具有超高稳定性的介孔材料越来越受到人们的重视.本文对高温水热合成有序介孔材料的发展过程作一个简单的综述,合成路线包括使用碳氟表面活性剂和碳氢表面活性剂作为复合模板,有机季铵盐与碳氢表面活性剂作为复合模板以及最近报道的采用碳氢表面活性剂作为单一模板来合成系列的有序介孔材料,其组成为二氧化硅、氧化钛硅以及聚合物等.

The hydrothermal synthesis of ordered mesoporous materials with high stability at high temperatures is currently a hot topic in the materials field.This review covers recent developments in the synthesis of ordered mesoporous silicas, titanosilicates and polymer materials with high hydrothermal stability at high temperatures.The uses of fluorocarbon and hydrocarbon surfactant mixtures and solo hydrocarbon surfactants are also discussed.
