Abstract

A series of carbonized PAF-1s were obtained with enhanced gas storage capacities and isosteric heats of adsorption (Q_st for short). Especially, PAF-1-450 can adsorb 4.5 mmol g^-1 CO₂ at 273 K and 1 bar. Moreover, it also exhibits excellent selectivity over other gases. On the basis of single component isotherm data, the dual-site Langmuir-Freundlich adsorption model-based ideal adsorption solution theory (IAST) prediction indicates that the CO₂/N₂ adsorption selectivity is as high as 209 at a 15/85 CO₂/N₂ ratio. Also, the CO₂/CH₄ adsorption selectivity is in the range of 7.8-9.8 at a 15/85 CO₂/CH₄ ratio at 0 < p < 40 bar, which is highly desirable for landfill gas separation. The calculated CO₂/H₂ adsorption selectivity is about 392 at 273 K and 1 bar for 20/80 CO₂/H₂ mixture. Besides, these carbonized PAF-1s possess excellent physicochemical stability. Practical applications in capture of CO₂ lie well within the realm of possibility.
