摘要：
A series of mesoporous Ti-MCM-41 materials was prepared at hydrothermal conditions (HT) as well as room temperature (RT). A constant Si/Ti ratio (26.1) in the initial gel and varying amounts of ammonium sulfate (SO(4)/Si = 0, 0.01, 0.1, 0.3, 0.5) were used. For solids prepared at SO(4)/Si below 0.3 their XRD spectra showed the pattern of a MCM-41 hexagonal array. The structural order decreased as the amount of sulfate increased. In materials prepared at RT higher sulfate concentrations favored the insertion of Ti and the wall thickness while the surface area decreased.
