Metal-Organic Framework-Based Membranes for the Separation of Light Gases
Metal-organic-frameworks (MOFs) are a class of coordination compounds which exhibit high porosity and a regular crystalline geometry resulting in open pore channels and high surface area. Pore sizes are typically on the order of molecular diameters and MOF pore surfaces are known to adsorb gases such as hydrogen, nitrogen, methane and carbon dioxide. These characteristics make them potential candidates for use as gas separation membranes. In this presentation, we will discuss our results on the use of MOFs as membranes for the separation of light gases. Specifically, membranes of Cu3(benzene-1,3,5-tricarboxylate)2 were fabricated and gas permeance experiments were performed. Experimental results indicate selectivity for adsorbing gases and potential transport mechanisms will be discussed.
