Improvement of Hydrogen Permeability with Mixed Matrix Membranes Containing Metal Doped MOF-5

Hydrogen is seen as the energy carrier of the future with its high energy density and envrironmental friendly properties. Since hydrogen is not pure in nature, it can be separated from the gas mixture by various techniques. Membrane technology involved in hydrogen separation processes has attracted attention in recent years thanks to its energy efficiency and mechanical strength. It has been found that the mixed matrix membranes formed by the addition of the filler material inside the membrane technology improve the gas separation properties. MOF structures used as a filler material are also preferred due to their high surface area and pore volume and have a positive effect on gas permeability. In this work, NiCoMOF-5 structure was synthesized using two different metals. Then, NiCoMOF-5 was added into polyimide membrane to prepare a mixed matrix membrane. The obtained MOF and MMM structures were evaluated various characterization procedures. The results show that the mixed matrix membrane is successfully synthesized and that the MOF added polyimide membrane improves the gas permeability performance relative to the pure polyimide
