Metal organic framework composite aerogel material and preparation method thereof

The invention relates to a metal organic framework composite aerogel material as well as a preparation method and application thereof. The metal organic framework composite aerogel material comprises an organic fiber material and a metal organic framework material, and the organic fiber material with carboxyl groups and the metal organic framework material form metal coordination bond connection through the carboxyl groups. The metal organic framework material grows and extends on the surface of the organic fiber material with the carboxyl group in situ to form a mesoporous structure. The organic fiber material is used as a matrix, so that the problem of insufficient toughness of the traditional inorganic material is solved. The metal organic framework material with a mesoporous structure is formed on the surface of the fiber, so that the heat resistance of the aerogel material is improved. The organic fiber material and the metal organic framework material are in coordination connection through carboxyl and
