| Outline of Final Research Achievements |
We developed the polymer composites composed of polymer and porous nanoparticles for CO2 capture applications. We investigated the various impurities impacts on gas separation performance of the composite membranes. We show that common impurities found in power station flue gases (H2S, SO2, and NO) have significant effects upon the performance of these polymer composite membranes. The effects of NO, SO2 and H2S on ZIF-8 are all large and rapid and would render these membranes unsuitable for flue gas service. Similarly, H2S appears to adsorb irreversibly into membranes containing Cu-BTC, although the impacts of NO and SO2 are less severe. The membranes containing POP-2 or porous carbon are less affected by these contaminants. These results suggest that polymer composites prepared using organic nanoparticles can be effective in gas separation applications such as natural gas sweetening, biogas purification and post-combustion carbon capture, when these impurities are present.
