New Poly(ionic liquid) Materials Increase CO2 Capture Efficiency

Researchers from Tohoku University and Nitto Boseki have developed a method to enhance carbon dioxide absorption using Poly(ionic liquid)s (PILs). By purifying the materials and increasing the size of the counter anions, the team achieved a CO2 adsorption capacity seven times higher than standard raw materials. This discovery provides a new design framework for creating more efficient gas separation membranes and carbon recovery devices. The findings could help lower the energy and cost requirements for capturing industrial emissions and atmospheric carbon.
