| Abstract: | A new titanium-containing MCM - 41 - type ultra - large porous molecular sieve has been synthesized by the hydrothermal method. It is confirmed that titanium located at framework positions by means of XRD, IR, DR UV-VIS 29Si MAS NMR techniques. The influences of Na+ and Al3+ ions on the synthesis of TiMCM-41 have been studied. The thermal stability, adsorption capacity and catalytic activity of the molecular sieve have also been elucidated. |
