Process for preparing mesoporous materials

摘要

A process for preparing a mesoporous material comprises the step of preparing a sol and treating the sol material under supercritical fluid conditions. The treatment under supercritical fluid conditions forms an ordered mesoporous material. The sol may be applied to a substrate to form a mesoporous film and subsequently treating the film under supercritical fluid conditions. Alternatively the process may comprise directly treating the sol under supercritical fluid conditions to form a mesoporous powder material.
