A novel nitrogen rich porous aromatic framework for hydrogen and carbon dioxide storage

A nitrogen rich, p-phenylenediamine based, porous aromatic framework (NPAF) with 1790 m2 g−1 BET surface area has been synthesized by using a Yamamoto coupling technique. The NPAF has shown a hydrogen uptake of 1.87 and 0.33 wt% at 77 K per 1 atm and 298 K per 80 bar, respectively. The CO2 uptake and selectivity of the NPAF at 273 K per 1 atm is 3.64 mmol g−1 and 48, respectively.
