介孔磷酸盐分子筛的合成研究进展

摘要

More attention has been focused on the application of mesoporous phosphates in various fields espe-cially as catalysts.But the poor thermal stability because of amorphous pore wall hinders its futher development and industrialized application.In this review,the synthesis route of mesoporous phosphates have been classified based on synthesis mechanism and the synthetic methods and strategies on mesoporous phosphates in aqueous and nonaqueous solution have been introduced respectively.The synthesis conditions play an important role in the mesostructure and thermal stability,which should not be ignored.Finally,several novel synthesis methods have been introduced.%介孔磷酸盐材料在催化领域的应用越来越受到人们的关注，但介孔材料非晶态的孔壁结构导致其热稳定性较低，是制约其发展和工业化应用的重要因素。从合成机理的角度对介孔磷酸盐的合成方法进行了分类，分别综述了水热合成技术和非水合成技术制备介孔磷酸盐材料的方法，分析了合成条件对其介孔结构和热稳定性的影响，介绍了几种合成介孔磷酸盐材料的新方法。
