Abstract:
1. A method for fabricating a high specific surface area alumina, which includes the following steps of: (A) providing a fluoro-surfactant of the following formula (I) or that of the following formula (IV): wherein m and n are integers between 1 and 10; (B) dissolving an aluminum salt and said fluoro-surfactant in water to form a solution, wherein the molar ratio of said fluoro-surfactant to said aluminum salt is 0.002-0.2:1; (C) adjusting the PH value of said solution to 6.0-8.0, by which to produce a precipitate in the solution; (D) heating said solution at the temperature of 70° C.-110° C. to proceed aging; (E) washing said precipitate with water; (F) washing said precipitate with an organic solvent that can be miscible with water in order to replace the water content in said precipitate; (G) drying said precipitate; and (H) sintering said precipitate at the temperature of 500° C.-1000° C.
