PREPARATION METHOD OF N-DOPED ACTIVATED CARBONS FOR CARBON DIOXIDE CAPTURE

摘要

The present invention relates to a preparation method of nitrogen-doped activated carbon for collecting carbon dioxide, more specifically, to a preparation method of nitrogen-doped activated carbon which is used as a carbon dioxide adsorbent including polymer as a raw material, which improves absorption efficiency of the carbon dioxide. The activated carbon manufactured according to the present invention is doped with a nitrogen functional group, induces acid-base interaction between an absorber and carbon dioxide, selectively absorbs carbon dioxide, and prevent the adsorption of various gases. Moreover, the activated carbon can be used as a carbon dioxide adsorbent catalyst and a catalyst by improving adsorption efficiency of carbon dioxide by maximizing micropores of the activated carbon and changing nitrogen content and the distribution of pores.
