Notes & Highlights:
  • FCTF-1 has one of the highest physisorptive (Q0st, FCTF-1 = 35 kj/mol) CO2 capacities ever recorded: 5.53 mmol/g at 273 K and 1 bar (1.76 at 0.1)
  • CO2/N2 selectivity increased when mixed gas measured compared to pure gas calculations. This verifies a 2011 observation by Guiver et al.
  • Moisture (0.03 bar, % 100 RH) lowered CO2 uptake 12 % at 298 K.
