Organic compounds is one of the rapid growing fields of interest from few decades with the introduction of most efficient and economical material for CO2 capture and storage. Here in, porous organic polymer based on melamine (MBPP) was prepared by single step polycondensation of isophthalaldehyde and 2,4,6-triamino-1,3,5-triazine via Schiff base chemistry. The synthesized polymer was subjected to pyrolysis at 800oC to produce nitrogen rich porous carbon (NRC). The fabricated materials were characterized by FTIR, XRD, XPS, FESEM, TGA, elemental analysis and BET measurements. CO2 measurements were performed on designed materials and optimum uptake was achieved to be 128.37 mg/g (2.91 mmol/g) at 273k and 1 bar pressure with the specific surface area of 445 m2/g. The excellent capturing ability and selective adsorption of CO2 over N2 was attributed to the presence of basic nitrogen ring in polymer chain and microporous texture of as prepared materials. |
