Fig. 6. CO2 capture performance of POPs containing heteroatoms with various parameters. (a) CO2 adsorption at 273 K versus total pore volume (Vtotal) and micropore volume ratio (Vmicro/Vtotal). (b) CO2 adsorption at 273 K versus total surface area (Stotal) and micropore surface area ratio (Smicro/Stotal). (c) Heat of adsorption (CO2Qst) and total surface area (Stotal) versus total heteroatom ratio (X/C, X = all heteroatom species in the same POPs) (d) CO2/N2 selectivity at 273 K and total surface area (Stotal) versus total heteroatom ratio (X/C, X = all heteroatom species in the same POPs) (e) heat of adsorption (CO2Qst) versus heteroatom ratio (X/N, X = F, O, S). (f) CO2/N2 selectivity versus heteroatom ratio (X/N, X = F, O, S). All the data is summarized in the Table 1.
