Outline of Final Research Achievements

The CO2 separation or capture from flue gases by the technology is of great interest from the perspective of greenhouse gas emissions and environmental health. At least approximately 20% of CO2 reduction is expected to be able to be achieved by applying Carbon dioxide Capture and Storage (CCS) using the membrane technology. The fabrication of mixed matrix membranes (MMMs) has been investigated intensively with a view to using for the gas separation applications such as the capture of carbon dioxide. We have demonstrated that the gas permeable separation membrane containing surface-modified non-porous pearl-neckless nanoparticles (P-NP) showed outstanding CO2 permeability (16,000 Barrer) with moderate CO2/N2 selectivity (>15). This strategy of nanoparticle with large gas permeable space may be applied to fabrication of MMMs for CCS and CCU (Carbon Dioxide Capture and Utilization).
