Abstract
Disclosed herein are methods for the preparation of porous metal oxide materials, including metal oxide xerogels and metal oxide aerogels. Methods for preparing porous metal oxide materials can comprise (i) reacting a metal alkoxide with water in the presence of a catalyst system to form a partially hydrolyzed sol, (ii) contacting the partially hydrolyzed sol with a base catalyst and a non-aqueous solvent to form a precursor gel; and (iii) drying the precursor gel to form the porous metal oxide material. The catalyst system employed in step (i) comprises a combination of a weak acid and a strong acid.
