英文摘要	The preparation of mesoporous zirconia with high surface area, large and tunable pore size and enhanced high thermal stability by controlled sol-gel method and post-synthesis treatment with aqueous ammonia was reported. the effects of preparation parameters, such as ph, aging temperature and the mole ratio of diglycol/zirconium (iv) n-propoxide on properties of the mesoporous materials were systematically investigated. it was found that the resultant materials possessed bet surface area as high as 406 m(2.)g(-1) and pore sizes ranging from 3.2 nm to 17.8 nm. furthermore, the sample prepared at ph 2.4 and 40 degrees c showed high thermal stability. after calcination at 700 degrees c for 4 h in air, the obtained material gave bet surface area of 195 m(2.)g(-1) and pore size up to 15.0 mn.
