摘要：Ti-doped MCM-41 mesoporous molecular sieve was synthesized in the presence of ammonia using TiCl3 as titanium source and TEOS as silica source. The synthesis method was simple, and it needed neither auxiliary templates nor alcohols. The molecular sieve was characterized by XRD and N-2 adsorption/desorption isotherms techniques. The results showed that the synthesized MCM-41 had hexagonal mesostructure with long-range order and good crystallinity. UV-Vis spectra indicated that four clear absorption peaks appeared in the range of 200 similar to 300 nm, which gave the facts that there existed different forms of Ti atoms doped in the framework of Ti-MCM-41.
