For the past few years, more and more articles about charged nanofiltration membranes and ordered mesoporous materials were reported in worldwide. Charged nanofiltration membranes get sieving effect and electric charge effect by their features of nanometer diameter holes and charged surface. Mesoporous materials have characteristics of ordered pore structures and narrow pore size distribution. The mesoporous molecular sieve which we are talking about in this article is a new-type of mesoporous mater...
