Amino functionalized zeolitic tetrazolate framework (ZTF) with high capacity for storage of carbon dioxide

A three dimensional -NH2 functionalized Zeolitic Tetrazolate Framework (ZTF-1) has been reported. The framework adopts a dia topology (M-L-M angle is close to 156 degrees). ZTF-1 shows high CO2 (273 K) and H-2 (77 K) uptake due to the presence of the free -NH2 group and uncoordinated tetrazolate nitrogen.
