A vertically-stacked MXene/rGO composite membrane for highly efficient H2/CO2 separation

Chem Commun (Camb). 2024 May 9;60(39):5177-5180. doi: 10.1039/d4cc00481g.

Abstract

A vertically-stacked MXene/rGO composite membrane with ultrashort transport channels is reported here, which demonstrated outstanding molecular sieving, i.e., H2/CO2 selectivity of up to 83 together with high H2 permeance of 2.7 × 10-7 mol m-2 s-1 Pa-1 at 120 °C, highlighting its applicability for H2/CO2 separation in CO2 capture and sequestration.
