Porous liquids allow for efficient gas separation

Jointly with partners, a researcher of Karlsruhe Institute of Technology has developed 'porous liquids': Nanoparticles, that are able to separate gas molecules of different sizes from each other, float - finely distributed - in a solvent. The porous liquids may be processed into membranes that efficiently separate propene from gaseous mixtures. This could replace the energy-intensive distillation that has been the common procedure up to now. (Nature Materials, DOI: 10.1038/s41563-020-0764-y).
