Abstract
A method of forming a molecular separation device is provided. The method comprises growing or depositing a silica MFI zeolite coating on a ceramic support. The method further comprises growing a ZIF-8 coating on the silica MFI zeolite coating. Growing the ZIF-8 coating on the silica MFI zeolite comprises applying a first reactant fluid including a metal salt and a second reactant fluid including an imidazole reactant to the silica MFI zeolite coating. Growing the ZIF-8 coating on the silica MFI zeolite further comprises reacting the first and second reactant fluid with the silica MFI zeolite coating to produce the ZIF-8 coating. In certain implementations, at least a portion of the ZIF-8 coating is interspersed with a portion of the silica MFI coating. A molecular separation device including the ZIF-8 coating and the silica MFI zeolite is also disclosed.
