Inserting Amide into NOTT-101 to Sharply Enhance Volumetric and Gravimetric Methane Storage Working Capacity

Amide-functionalized NJU-Bai45 exhibits high volumetric and gravimetric CH 4 working capacities of 190 cm 3 cm –3 and 298 cm 3 g –1 (from 5.8 to 65 bar), higher than that of the similar NJU-Bai43 (187 cm 3 cm –3 and 292 cm 3 g –1 ). This finding indicates that nitrogen-functionalized aromatic ring may not always play a positive role in amide-MOF for CH 4 storage.
