The mesoporous carbon nanomaterials obtained from waste onion peels confirmed the formation of mesoporous carbon nanospheres (CNSs) with an average pore diameter of 2 nm. The as obtained CNSs were studied to demonstrate their ability to adsorb the greenhouse gas CO 2 at different temperatures, 30, 40 and 50 °C. The results showed that the CNSs have high potential to adsorb CO 2 at these temperatures. Present work demonstrates the formation of sustainable, porous adsorbents by a simple waste to wealth based approach that is effective for the adsorption of CO 2 .
