摘要： 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.

摘要： 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.
