1. A method of forming a molecular separation device, comprising:
growing or depositing a silica MFI zeolite coating on a ceramic support, the growing or depositing comprising:
coating the ceramic support with a layer of 3D MFI nanoparticles; and
coating the layer of 3D MFI nanoparticles with a layer of 2D MFI nanosheets; and
growing a ZIF-8 coating on the silica MFI zeolite coating, the growing comprising:
applying a first reactant fluid including a metal salt and a second reactant fluid including an imidazole reactant to the silica MFI zeolite coating; and
reacting the first and second reactant fluids on the silica MFI zeolite coating to produce the ZIF-8 coating.
