A method for fabricating a high specific surface area mesoporous alumina is disclosed, which includes the following steps: (a) providing a water solution containing an aluminum salt and a fluoro-surfactant; (b) adding concentrated hydrochloric acid to adjust the PH value of the solution to about 6.0 to 8.0; (c) aging the solution at 70° C. to 110° C. for 12 to 20 hours; (d) washing the precipitate with water; (e) washing the precipitate with an organic solvent; (f) drying the precipitate; and (g) sintering the precipitate in a furnace of 500° C. to 1000° C.

Depending on the reaction conditions, the reaction of tetrakis(polyfluoroalkoxy)telluranes with acetic, trifluoroacetic, benzoic, and phthalic anhydrides gives acyloxy(polyfluoroalkoxy)telluranes or esters of acyloxytellurous acid, which are a new type of derivatives of tetra- and hexacoordinated tellurium.Polyfluorinated esters are also obtained in the reaction of acid anhydrides with (polyfluoroalkoxy)telluranes.
