The present invention provides a method for surface modification of a carbonaceous material such as activated carbon fiber with an increased proportion of active sites contributing to desulfurization or denitration, and a carbonaceous material or activated carbon fiber obtained thereby. The surface modification method for activated carbon fiber according to the present invention is a method for surface modification of a carbonaceous material having an oxygen functional group on the surface, wherein the oxygen functional group is generated by oxidizing the carbonaceous material. And deoxidizing the carbonaceous material surface to increase the active sites on the surface, oxidizing the carbonaceous material having an oxygen functional group on the surface to increase the oxygen functional group, The increased oxygen functional groups can be eliminated to increase the active sites on the surface of the carbonaceous material.
