New insight into mesoporous silica for nano metal-organic framework

A micropore- and mesopore-integrated material was synthesized by using a mesoporous silica and a metal-organic framework (MOF). The composite was composed of nano MOF crystals and mesoporous silica showing high porosity based on the intrinsic micropores of MOF and mesopores of mesoporous silica and additional pore spaces that should be from the void between nano MOF crystals. The composite shows higher adsorption rate of ethanol at 303 K than that of the bulk MOF.
