Porous Liquids Allow for Efficient Gas Separation

New material opens up the possibility of saving up to 80 percent of energy when separating raw materials for the plastics industry

14-Aug-2020

Jointly with cooperation partners, a researcher of Karlsruhe Institute of Technology (KIT) has developed “porous liquids”: Nanoparticles, that are able to separate gas molecules of different sizes from each other, float – finely distributed – in a solvent. This is because the particles have empty ...
