Synthesis of Ti-MCM-41 using colloidal silica and titanium trichloride - I. Synthesis of Ti-MCM-41 molecular sieve

silicon source and using TiCl3 solution as titanium source. Among the used auxiliary templates, tetramethylammonium hydroxide (TMAOH) and tetraethylammonium hydroxide (TEAOH) were found to be the most effective ones to improve the long-range order. Titanium content (molar fraction) in the Ti-MCM-41 can be up to 3.75% which is higher than that in Ti-MCM-41 synthesized from organic precursors.
