Abstract
A post-synthesis route, through which various metal elements can be grafted onto siliceous frameworks using non-aqueous solutions of AlCl3, Al(NO3)3, SnCl2, Zn(O2CMe)2 Mn(O2CMe)2, etc., is developed as a generalised means to obtain mesoporous metallosilicates molecular sieves with various structures such as MCM-41 (hexagonal), MCM-48 (cubic Ia3d), SBA-1 (cubic Pm3n), KIT-1 (disordered) and MSU-1 (disordered) with superior structural integrity, acidity and catalytic activity to those of materials having metals incorporated during synthesis.Keywords
