a Adsorption and desorption isotherms for four Al-MOFs at 298 K (red: MIL-160; blue: CAU-10-H; magenta: Al-fum; olive: MIL-53(Al); solid: adsorption; open: desorption). b Adsorption and desorption isotherms for MIL-160 at 273−308 K (red: 273 K; blue: 283 K; magenta: 298 K; dark yellow: 308 K; solid: adsorption; open: desorption). c Dynamic breakthrough plots for NH3 (1000 ppm diluted in He) with an inlet gas flow rate of 25 mL min−1 through a fixed-bed packed with (olive) MIL-53(Al), (magenta) Al-fum, (blue) CAU-10-H and (red) MIL-160 samples at 298 K. d Plots for isosteric heats of adsorption (Qst) and entropies of adsorption (∆S) (red: Qst; black: ∆S). The error bars were derived by least-squares linear fitting from four isotherms at different temperatures.
