Study of CO2 Adsorption in Low Cost Graphite Nanoplatelets

Ashish Kumar Mishra and Sundara Ramaprabhu

Abstract—The growing needs of fossil fuel energy pose a great challenge in the control of CO2 emissions in our atmosphere. Adsorption can be considered to be one of the more promising methods for CO2 capture. In the present work, graphite nanoplatets were prepared by acid intercalation followed by exfoliation technique. These graphite nanoplatelets were further functionalized and characterized by different characterization techniques. The CO2 adsorption capacity was measured by high pressure Seiverts' apparatus using vander Waals equation. Maximum adsorption capacity of 0.0036, 0.004 and 0.0049 mol/g was observed at 12 bar equilibrium pressure and at 100, 50 and 25 ºC temperature respectively. Isotherm deviates largely from Dubinin - Radushkevitch equation and hence suggests the adsorption via interaction with functional groups and gas condensation rather than micropore filling.
