A method for the adjacent electrodeposition of a metal-organic framework (MOF) on a porous membrane is disclosed. The method includes placing the porous membrane between a cathode and an anode in an electrodeposition setup with the porous membrane separated from the cathode by less than 6 mm, and introducing a solution having a ligand and a metal ion source into the electrodeposition setup, between the anode and the cathode. The method then includes applying a bias to the cathode to reduce water and deprotonate the ligand thereby increasing a concentration of metal cations and deprotonated ligand anions between the porous membrane and the cathode, resulting in the nucleation and growth of a MOF film directly on the porous membrane. The MOF film is conformal. The porous membrane is insulating polypropylene, the MOF is ZIF-8, the metal cations are Zn, and the deprotonated ligand anion is 2-methylimidazolate (MIM-).
