Porous liquids are a new class of liquid materials that contain microscopic cavities (pores), each the size of a single molecule. They contain up to 10 000 times the number of cavities that are found in conventional liquids, and up to around 20% of the liquid is actually empty space.
Thanks to these cavities, porous liquids can absorb large amounts of gas and they can be tuned to selectively absorb one gas over another — as for porous solids, which are widely applied in industry. However, a critical advantage over porous solids is that porous liquids can also flow through pipes, meaning that they can be applied in a host of different ways.
For example, they can be implemented in continuous flow separations or be drop-in replacements for liquid absorption systems based on conventional liquids, such as amine solutions.
