Abstract

The invention relates to an inorganic material with a hierarchical structure and to a sol-gel method for the preparation thereof. The material is monolithic and is comprised of an inorganic matrix. The matrix consists of a metal oxide polymer and comprises macro-pores, meso-pores and micro-pores, said pores being interconnected. The preparation method consists in preparing an emulsion by introducing an oily phase into an aqueous solution consisting of a surfactant and a metal alcoxide; the reaction mixture is left to rest until condensation of the precursor occurs; the mixture is subsequently dried and calcinated.
