A superb water permeable membrane for potential applications in CO2 to liquid fuel process

In this paper, a superb water permeable membrane is prepared by treating an alumina hollow fiber supported metal-organic framework (MOF) with hydrophilic ionic liquid (IL). For ternary mixture of H 2 O/CO /H separation, the IL layer separates O and CO from MOF functions as selective for further separation . Furthermore, owing to high hydrophilicity IL, permeation enhanced comparing pristine membrane. At extremely harsh conditions temperature up 200 °C pressure 20 bar, IL/MOF has achieved excellent vapor/gases performance, permeance 7.7*10 −8 mol m −2 s −1 Pa factor (~472 O/H ~280 ). Scheme 1.
