Researchers make a 'porous liquid'

Scientists at Queen¡¯s University have made a major breakthrough by making a porous liquid – with the potential for a massive range of new technologies including ¡®carbon capture¡¯.

Researchers in the School of Chemistry and Chemical Engineering at Queen¡¯s, along with colleagues at the University of Liverpool, UK, and other, international partners, have invented the new liquid and found that it can dissolve unusually large amounts of gas, which are absorbed into the ¡®holes¡¯ in the liquid. The results of their research are published today in the journal Nature ("Liquids with permanent porosity").

The three-year research project could pave the way for many more efficient and greener chemical processes, including ultimately the procedure known as carbon capture - trapping carbon dioxide from major sources, for example a fossil-fuel power plant, and storing it to prevent its entry into the atmosphere.

Professor Stuart James of Queen¡¯s School of Chemistry and Chemical Engineering said: ¡°Materials which contain permanent holes, or pores, are technologically important. They are used for manufacturing a range of products from plastic bottles to petrol. However, until recently, these porous materials have been solids. What we have done is to design a special liquid from the ¡®bottom-up¡¯ – we designed the shapes of the molecules which make up the liquid so that the liquid could not fill up all the space. Because of the empty holes we then had in the liquid, we found that it was able to dissolve unusually large amounts of gas. These first experiments are what is needed to understand this new type of material, and the results point to interesting long-term applications which rely on dissolution of gases.

¡°A few more years¡¯ research will be needed, but if we can find applications for these porous liquids they could result in new or improved chemical processes. At the very least, we have managed to demonstrate a very new principle – that by creating holes in liquids we can dramatically increase the amount of gas they can dissolve. These remarkable properties suggest interesting applications in the long term.¡±

Queen¡¯s University Belfast led the research which also involved the University of Liverpool and universities in France, Germany and Argentina. The study was mainly funded by the Leverhulme Trust and the Engineering Physical Science Research Council (EPSRC).
