| Abstract: | Pure silicon mesoporous molecular sieve MCM-41 had stable skeleton structure,orderly arranged pore rules and narrow pore size distribution. But due to its poor hydrothermal stability,weak acidity and small pore size,it was difficult to be used for macromolecular reaction. The latest research about modified mesoporous MCM-41 and its application were summarized,especially,focused on reaming modification,metal doping and heteropolyacid modification. |
