New insight into mesoporous silica for nano metal-organic framework

► MOF-mesoporous silica composites were synthesized in facile synthetic procedure. ► The composites show high porosity based on the intrinsic micropores of MOF and mesopores of mesoporous silica. ► The composites have additional pore spaces between nano MOF crystals. ► The composite shows higher adsorption rate of ethanol at 303 K than that of bulk MOF.
