Synthesis of Micro-Mesoporous Titanium-Silicon Molecular Sieve by Dual Templates Method

Article Preview

Abstract:

Micro-mesoporous titanium-silicon molecular sieve (MMTS) was synthesized through dual templates method. The physical characterization of MMTS was carried out by BET, FTIR, UV-Vis. The results showed that the MMTS samples synthesized by dual templates method possessed mainly micropores and some mesopores with pore size of 3.9 nm, but a portion of the titanium in the framework was removed as indicated from UV-Vis diffuse reflectance spectroscopy.
