Membrane technology has been widely used in industrial CO2 capturing, gas purification and separation, arousing attention due to its advantages of high efficiency, energy saving environmental protection. In the context reducing global carbon emissions combating climate change, it is particularly important capture separate greenhouse gasses such as CO2. Zr-MOF can be a multi-dimensional modification on polymer membrane prepare self-assembled MOF-based mixed matrix membranes (MMMs), aiming at problem weak adhesion or bonding force between separation layer porous carrier. When defective UiO-66 applied PVDF functional layer, performance significantly improved. TUT-UiO-3-TTN@PVDF permeation flux 14,294 GPU selectivity 27 for CO2/N2 18 CO2/CH4, respectively. The permeability exhibited change after 40 h continuous operation, improving showing exceptional stability large-scale applications.
