MANUFACTURING METHOD OF CARBON NANOTUBES IMPREGNATED WITH AMINEFUNCTIONS FOR CARBON DIOXIDE CAPTURE

摘要

The present invention relates to a method for producing carbon nanotubes having amine functional groups introduced thereto for capturing carbon dioxide. The method for producing carbon nanotubes having amine functional groups introduced thereto for capturing carbon dioxide comprises the steps of: (1) pretreating multi-walled carbon nanotubes by introducing the same into an acid solution; (2) mixing an amine group-containing precursor with an organic solvent, followed by agitation; and (3) introducing the carbon nanotubes pretreated in the step (1) into the solution of the step (2), followed by agitation. According to the method of the present invention, it is possible to obtain carbon nanocomposites for capturing carbon dioxide, characterized by CO_2 selectivity under the condition of exhaust gas, high adsorption capacity and high regeneratability during repeated adsorption/desorption processes.
