Green energy from solar, wind, and water in the nearest future will make a maximum contribution to global energy balance, substituting combustion technologies for energy production. However, considerable efforts need to be made in this direction, therefore, carbon dioxide caption technologies and hydrogen purification technologies are needed for a transition period to reduce the burden on nature. Hydrogen can be considered a green energy source. It can be obtained from water using electrolysis or hydrocarbons, alcohols, or biomass using gasification followed by water gas shift reaction. Hydrogen synthesized from water characterized by high purity and hydrogen obtained using water gas shift reaction needs to be purified from a mixture with water, carbon monoxide, and carbon dioxide. Pd-containing membranes and polymer membranes are well-known solutions for hydrogen purification. However, Pd-containing membranes are expensive, and polymer hydrogen separation membranes are sensitive to gas mixture composition and temperature. Ceramic and zeolite-based membranes can be considered as a cheap alternative for polymeric and Pd-containing membranes for hydrogen purification. On the other side ceramic and polymer-containing membranes are characterized by low CO2/H2 selectivity, this issue needs to be solved for their wide application. Here synthesis of MFI alumina supported membrane modified with copper oxide and zinc oxide is described. Membrane synthesis was performed using the hydrothermal treatment method of plate alumina support followed by impregnation of zinc and copper acetates solutions with further zinc and copper precipitation and oxidation to an oxide form. Separation factor and permeance measurements showed an increase of separation factor from 25 up to 42 in the case of copper incorporation.
