Pore size controlled mesoporous silicate powder prepared by triblock copolymer templates

The pore sizes of SBA-15 and SBA-16 are controlled well by the direct micelle control method, which is related with assembled conditions of the solution temperature and concentration of the triblock copolymer. The relation between the pore size of the mesoporous silicate and the assembled conditions is the same as that one among the core radius of the micelle,2 triblock copolymer, the solution temperature T and the critical micellization temperature T-c in similar to (T - T-c)(0.2) (C) 2002 Elsevier Science B.V All rights reserved.
