Abstract
Provided is a production method for a porous alumina material, comprising the steps of: mixing an alkoxysilane solution that comprises an alkoxysilane, a mixed solvent comprising water and an alcohol, and an inorganic acid, with an aluminum solution comprising an aluminum compound and water, to prepare a mixed solution in which the aluminum compound and the alkoxysilane are dissolved in the mixed solvent; co-precipitating aluminum hydroxide with a silicon compound in the mixed solution, to form a precipitate; and baking the precipitate to form a porous alumina material comprising aluminum oxide and silicon oxide.
