Today, existing power plants based on coal present in the world emit about 2 billion tons of CO2 per year. Because of its fundamental engineering and economic advantages in competing separation technologies, membrane operations are being explored for the separation of CO2 and other exhaust emissions of power plants based on fossil fuels. [1] The zeolite imidazolate framework (ZIFs) are novel microporous materials with different structures and pore sizes and large surface areas. Membranes of these materials have great potential for the separation of gas mixtures energy and environmental interest. [2-4]

This paper reports the synthesis and characterization of two potentially useful membrane separation of CO2 from the compound known as ZIF-8 and an amendment thereto using a mixture of metals (Zn and Co). This modification is expected to modulate the interaction enthalpy and thereby turn the selectivity of the membrane as a result of the involvement of two types of metals in the molecular lattice.
