沸石膜的合成最新进展

摘要

Strategies for the preparation of zeolite molecular membranes,such as in-situ hydrothermal synthesis,secondary growth,microwave synthesis and pulsed laser ablation,are reviewed.By comparison,their drawbacks are also pointed out Preparing thin and continuous films with nanopaticles is the ultimate goal.Programs for the pretreatment of substrates are summarized, and the methods of preparing zeolite membranes were prospected.%介绍了合成沸石膜的常用方法，如：原位水热合成法、二次生长法、微波法及脉冲激光烧蚀法，并对各种方法进行了比较，指出了其优缺点。提出了沸石膜合成的目标：合成由小晶粒组成的薄而连续的定向膜。对载体的选择及处理方法进行了总结，并对沸石膜的合成方法进行了展望。
