A Triazole Functionalized txt-Type Metal–Organic Framework with High Performance for CH4 Uptake and Selective CO2 Adsorption

The metal-organic framework (MOF) NTUniv-54 (NTUniv = Nantong University) was assembled via utilizing click chemistry with densely decorated trizole units and exposed metal sites, which exhibited the best methane working ability (197 cm³·cm^-3 from 100 to 5 bar and 177 cm³·cm^-3 from 65 to 5 bar at 298 K), and the lowest CO₂ Q_st of 22.8 kJ·mol^-1 in all triazole-MOFs at room temperature.
