METHOD FOR PREPARING CARBON MATERIAL, DOPED WITH HETERO ELEMENTS, FROM FLUE GAS CONTAINING CARBON DIOXIDE

摘要

The present invention relates to a method for preparing a carbon material, doped with hetero elements with excellent oxygen reduction reaction activity and electrical energy storage capacity, from flue gas containing carbon dioxide without pretreatment or separation of carbon dioxide. The method of the present invention can prepare a carbon material with excellent redox reaction capacity directly from flue gas without pretreatment or separation of carbon dioxide. In addition, the present invention is an economical process capable of reducing energy compared with a conventional preparation process by synthesizing a carbon material from carbon dioxide under moderate atmospheric pressure conditions. A carbon material prepared by the present invention is doped with a plurality of hetero elements with excellent redox reaction activity, and thus can be used as a catalyst of a fuel cell. In addition, a carbon material prepared by the present invention has pores having a high surface area and a large volume, and thus can be used for energy storage such as a supercapacitor or a hydrogen storage device. Additionally, the preparation method of the present invention is economical and environmentally friendly since the preparation method can produce a high-value carbon material by using flue gas containing carbon dioxide and can block the release of carbon dioxide into the air.
