Novel graphene-based filters to make gas purification more effective

Nanowerk  March 27, 2020
Precise molecular sieving is potentially possible using graphene oxide‐based membranes, if the porosity can be matched with the kinetic diameters of the gas molecules, which is possible via the tuning of graphene oxide interlayer spacing to take advantage of gas species interactions with graphene oxide channels. An international team of researchers (Australia, South Korea) have shown highly effective separation of gases from their mixtures by using uniquely tailored porosity in mildly reduced graphene oxide (rGO) based membranes. The study will lead to new avenues for the applications of graphene for efficiently separating CO2 from N2 and other gases…read more. TECHNICAL ARTICLE
