Separation of CO2 from CH4 and CO2 capture in the presence of water vapour in NOTT-400

From a binary equimolar gas-mixture of CO2 and CH4, NOTT-400 shows CO2 separation from CH4. By kinetic uptake experiments, this material confirms a maximum of 4.3 wt% CO2 capture at 30 degrees C and a significant 2-fold increase (similar to 9.3 wt%) in CO2 capture under 40% relative humidity of water vapour.
