  • Patent number: 10710884
    Abstract: The present invention relates to a method of preparing a metal oxide-silica composite aerogel having a uniform particle size and excellent pore characteristics and a metal oxide-silica composite aerogel prepared thereby. The preparation method according to the present invention may not only have good economic efficiency because production costs are relatively reduced in comparison to the related art, but may also effectively prevent the collapse of a pore structure by suppressing a shrinkage phenomenon during drying. Thus, a metal oxide-silica composite aerogel prepared by the above preparation method may have higher specific surface area and better pore characteristics than a conventional metal oxide-silica composite aerogel prepared by oven drying while having low tap density.
