英文摘要	The mesoporous SiO2 xerogels with controlled texture were obtained using TEOS as precursor in the presence of Polyethylene Oxide (PEO)- Polypropylene Oxide (PPO)- Polyethylene Oxide (PEO) by sol-gel method. By means of BET, TG/DTA, FT-IR and Si-29 NMR analysis, the sol-gel chemistry was investigated and the effects of heat treatment in different conditions were also discussed. The results show that the triblock copolymer molecular chain, additive amount and ageing time of SiO2 sol can adjust available the texture properties of mesoporous SiO2, and in different atmospheres, the removed mechanism of such copolymer is different, which results in the different effects on the mesoporous SiO2. As a result, the mesoporous SiO2 has stronger flexible skeleton, narrower pore distibution, and higher thermal stability by vacuum heat-treatment.
