Abstract
The newly Ni++-1,3,5-tribenzyl-1,3,5-triazine-2,4,6-(1H,3H, 5H)-trione coordinated polymeric MOFs were carefully synthesized via microwave-assisted hydrothermal technique. Theoretical investigations were predicted by two different stereo-orientations which can be present inside unite cell of Ni(II)-MOFs, one of them (wings like structure) is strongly recommend to form 3D-Ni(II)-1,3,5-tribenzyl-1,3,5-triazine-2,4,6-(1H,3H, 5H)-trione coordinated polymeric MOFs. The synthesized amorphous Ni-MOFs were characterized by mass spectroscopy, Uv/Vis spectra, scanning electron microscope (SEM) and three dimensional atomic force microscope (3D-AFM). Furthermore BET specific surface area was measured and found 3181 m2/g. Ni(II)-MOFs exhibit high adsorption capacity for carbon dioxide uptake recording a maximum adsorption capacity of 118.2 mg CO2/g of Ni(II)-aMOFs at 30 °C, 27 bar.
