Abstract Siliceous MCM-41 mesoporous materials and those possessing Fe, La, Al,respectively, were synthesized using water glass as silica source. Results from thermogravimetric analysis and other techniques showed us that Fe(III) or La(III) species was incorporated into framework. Owing to Fe–O or La–O bond longer than Si–O bond, Fe(III) or La(III) species was limited to insert into framework and transformed from tetrahedrally coordinated state to octahedrally coordinated state upon calcination to remove template.
