    Abstract: Provided are a method of preparing a metal oxide-silica composite aerogel, and a metal oxide-silica composite aerogel having an excellent weight reduction property prepared by the method. The method includes a step of adding an acid catalyst to a first water glass solution to prepare an acidic water glass solution (step 1); a step of adding a metal ion solution to the acidic water glass solution to prepare a precursor solution (step 2); and a step of adding a second water glass solution to the precursor solution and performing a gelation reaction (step 3) to yield a metal oxide-silica composite wet gel, wherein, in steps 2 and 3, bubbling of an inert gas is performed during the adding of the metal ion solution or the second water glass solution, respectively.

    Abstract: The present invention relates to a method of preparing a hydrophobic metal oxide-silica composite aerogel, in which a degree of hydrophobicity may be controlled while having a high specific surface area and a low tap density, and a hydrophobic metal oxide-silica composite aerogel prepared thereby. The preparation method according to the present invention may not only have excellent productivity and economic efficiency due to a relatively simpler preparation process and shorter preparation time than the related art, but may also perform an effective surface modification reaction by using a small amount of a surface modifier. Thus, since the surface modification reaction may be easily performed by using only a very small amount of the surface modifier, a hydrophobic metal oxide-silica composite aerogel containing about 1 wt % to 2 wt % of carbon may be prepared.
