Abstract

The metal organic framework (MOF) materials HKUST-1, CAU-10, MIL-101(Cr) and UiO-66(Zr) were successfully coated onto open cellular silanized alumina and oxide bonded silicon carbide foams by a direct crystallization approach. Two different silanization routes were tested with respect to the functional group of the silane molecule used. For the HKUST-1 and CAU-10 based composite materials the influence of the foam material, its pore size and pore density and its surface chemistry on the amount of deposited MOF material and its water uptake capacity was evaluated. Based on these data in combination with micro computertomograpy results a model was developed to estimate the MOF coating thickness on cellular supports.
