  • Method for fabricating porous composite oxide
    Patent number: 5962352
    Abstract: A method for fabricating a porous composite oxide is provided. The method includes the steps of: (a) slowly mixing a solution including a silicon oxide source and a solution including an aluminum oxide source; (b) adding hydrochloric acid to the mixed solution prepared in said step (a) to obtain a sol; and (c) adding sodium hydroxide to said sol, reacting the obtained resultant at room temperature for 30 minutes to 12 hours, and drying the resultant. The porous composite oxide has an abundance of fine pores and the distribution of pore size is relatively uniform, so that the porous composite oxide is suitable for a carrier.
