摘要
综述了空间限制法在制备纳米沸石方面的应用,主要介绍了微乳法与反胶束法的机理及其在合成纳米沸石方面的应用,以及惰性介质空间限制法与水凝胶制约法在小晶粒沸石合成方面的研究现状。采用这些方法合成的纳米沸石粒径较小,且分布均匀,大小可调。另外还归纳了这3类空间限制法在纳米沸石合成中的共同特点,比较了其优缺点,并对其应用前景进行了展望。
Three confined space methods for synthesis of nano-zeolites, namely microemulsion or reverse micelle method, confined space method in inert medium and confined space method in polymer hydrogels, were reviewed. Principles of these methods and their applications in synthesis of nano-zeolite were introduced. Adjustable size and uniformity of nanozeolites could be achieved by applying these methods. Features of these methods for Synthesis of nanozeolites were summarized and compared. Their application prospect was proposed.
