| description | Membrane technology has been widely used in industrial CO<sub>2</sub> capturing, gas purification and gas separation, arousing attention due to its advantages of high efficiency, energy saving and environmental protection. In the context of reducing global carbon emissions and combating climate change, it is particularly important to capture and separate greenhouse gasses such as CO<sub>2</sub>. Zr-MOF can be used as a multi-dimensional modification on the polymer membrane to prepare self-assembled MOF-based mixed matrix membranes (MMMs), aiming at the problem of weak adhesion or bonding force between the separation layer and the porous carrier. When defective UiO-66 is applied to PVDF membrane as a functional layer, the CO<sub>2</sub> separation performance of the PVDF membrane is significantly improved. TUT-UiO-3-TTN@PVDF has a CO<sub>2</sub> permeation flux of 14,294 GPU and a selectivity of 27 for CO<sub>2</sub>/N<sub>2</sub> and 18 for CO<sub>2</sub>/CH<sub>4</sub>, respectively. The CO<sub>2</sub> permeability and selectivity of the membrane exhibited change after 40 h of continuous operation, significantly improving the gas separation performance and showing exceptional stability for large-scale applications. |
