| 英文摘要 | Al-SBA-15 with a rod-like morphology and well-ordered mesostructure was hydrothermally synthesized through a one-step approach in an environmentally friendly medium by using triblock copolymer Pluronic P123 as a structure-directing agent. The influence of aging temperature and silica-alumina species co-hydrolysis on the morphologies and structural properties of the resultant materials were investigated by XRD, IR, SEM, TEM and nitrogen adsorption-desorption techniques at 77 K. Compared to silica-alumina co-hydrolysis, the aging temperature plays an important role in the formation of the ordered mesostructure. The mesopores are widened and the wall thickness becomes thinner when the aging temperature is increased. The particles have well-defined rod-like morphology with the uniform particle size from 2 to 4 m and the diameter in the range of 400 similar to 600 nm. The Si/Al molar ratio of the final Al-SBA-15 samples will be obviously higher if the time for silica-alumina co-hydrolysis is longer than 20 h. |
