摘要: The preparation of a mesoporous molecular sieve MCM-41 both with bimodal framework and textural mesopores high thermal stability that results from thicker wall has been achieved by decreasing surfactant/silicon ratio synthesis gel. resultant material retains porosity large BET surface area even after treatment at 1273 K for 1 h in air.
