J. Yu et al., Preparation of high thermal stability MCM-41 in the low surfactant/siliconmolar ratio synthesis systems, MATER LETT, 48(2), 2001, pp. 112-116
The preparation of a mesoporous molecular sieve MCM-41 both with bimodal fr
amework and textural mesopores and with high thermal stability that results
from a thicker wall has been achieved by decreasing surfactant/silicon rat
io of synthesis gel. The resultant material retains porosity and large BET
surface area even after thermal treatment at 1273 K for I h in air. (C) 200
