Abstract: | This paper is a review of studies on aerogel synthesis and its application for catalytic uses, which have been conducted for
the past decade at the Clean Technology Research Center, Korea Institute of Science and Technology. Various organic and inorganic
aerogels employing sol–gel modifications exhibited catalytically favorable textural and chemical properties such as extremely
high porosity, high surface area, well-developed mesoporosity, good thermal stability, and high dispersion, which eventually
led to excellent performance in catalytic reactions. Reactions observed in these studies include hydrogenation, photodecomposition,
selective oxidation, complete oxidation, ammoxidation, reforming, and electrooxidation. The specific catalytic behaviors can
be explained in terms of the strong active sites-support interactions, high thermal stability, and extremely high dispersion. |
