dc.description.abstract | Valorization of waste polyethylene terephthalate (PET) plastic into microporous carbon with N-doping treatment was successfully performed in a one-pot synthesis and the N-doped microporous carbon was used for CO2 capture, which can mitigate plastic pollution and climate change simultaneously. The PET-derived microporous carbon developed by KOH activation and urea treatment in a one-pot synthesis at 700 degrees C exhibited the highest CO2 adsorption uptake of 6.23 mmol g(-1) at 0 degrees C and 4.58 mmol g(-1) at 25 degrees C (1 aim). The Langmuir and pseudo second-order models displayed well-fitting relationships with equilibrium and kinetic experimental data obtained in this study. The N-doped microporous carbon showed high CO2 selectivity over N-2, implying that it is feasible for treating flue gases (10% CO2 and 90% N-2) at 50 degrees C. In addition, the CO2 uptake was not only affected by micropores but also related with nitrogen and oxygen functional groups. Compared to the porous carbon prepared by two-pot synthesis where KOH activation and urea treatment were conducted separately, the porous carbon prepared by one-pot synthesis had higher oxygen contents and higher CO2 adsorption uptake. All of findings implied that the N-doped microporous carbon was successfully developed from waste PET plastic for capturing CO2 and can play a promising role in both sustainable waste management and environmental protection. | - |
