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.
