Fig. 3 — a N₂ sorption isotherms at 77 K and b CO₂ sorption isotherms at 273 K of polyUiO-66 samples (filled symbols: adsorption and unfilled symbols: desorption). c Brunauer–Emmett–Teller (BET) surface area of polyUiO-66 samples calculated from N₂ sorption isotherms and CO₂ sorption isotherms, respectively. d Non-local density functional theory (NLDFT) pore size distributions of polyUiO-66 nanoparticles calculated from the CO₂ adsorption isotherm at 273 K. Gray squares highlight the pore size range between 3 to 4 Å. Note that polyUiO-66(0:1) was excluded for CO₂ sorption studies due to its essentially non-porous nature.
