چکیده انگلیسی
Mesoporous alumina has been synthesized by traditional precipitation method using aluminum nitrate and aluminum sulfate. Ammonium carbonate was used as precipitator. The characterization showed that the ordered worm-like pores are obtained, surface area reached about 250–300 m2/g, and narrow pore size distributions centered at 6 nm. The experimental results indicated that the structure of mesoporous alumina was related to precursor which was dominated by the source of alumina and pH value. The structure change of precursor and calcination process were discussed. A self-assembly mechanism is proposed for the formation of this materials.
