"非经典"分子筛----物质高效分离新技术研究综述.

Molecular sieves, a type of material with porous structure, are able to separate small molecules. Classical molecular sieves have been investigated thoroughly, but they have limitations as well. For example, they are unable to separate chemicals with similar physical properties. In recent years, scientists have begun to focus on "nonclassical" methods for chemical separation. Many achievements have been made, such as microporous membranes, porous liquid and cage-like molecules. Some of these methods may greatly reduce the cost of industrial production and even have a great influence on social and economic development. In this review, the novel methods are discussed, and the development trend of this research field is provided. [ABSTRACT FROM AUTHOR]
