摘　　要：综述了各种外场作用(包括微重力技术、超重力技术、旋转液膜技术、超声波技术、微波技术、紫外和电场)对分子筛合成过程、结构特性和催化/吸附应用性能影响,以及作用机制等方面的研究进展。结果表明:外场作用下有利于合成小粒径、大比表面积、高孔隙率和多活性位点的分子筛吸附/催化材料,结合自身应用前景,超重力技术、微波技术和旋转液膜技术为高效绿色合成高性能分子筛提供了新的技术支持。In this paper,the effects of various external field conditions(including micro-gravity technology,high-gravity technology,rotating liquid film technology,ultrasonic waves technology,microwave technology,ultraviolet radiation technology,and electric fields)on molecular sieves synthesis processes,structural properties,catalytic/adsorption performance,as well as the mechanisms are reviewed.The results show that the application of external fields promotes the production of molecular sieve adsorbents/catalysts with smaller particle sizes,larger specific surface areas,higher porosities,and more active sites.Considering the promising applications of these technologies,high-gravity technology,rotating liquid film technology and microwave technology provide new technical supports for the efficient synthesis of high-performance molecular sieves.
