A highly crystalline graphitized carbon support including carbon particles including a highly crystalline graphitized layer, the highly crystalline graphitized layer comprising a functional group bonded to the surface thereof, the functional group comprising a compound represented by the following chemical formula 1:
- —Ar—(R)n Chemical formula 1
- wherein Ar is alkylene or arylene, R are each independently a hydrogen atom or a substituent comprising any one hetero atom selected from the group consisting of nitrogen, sulfur and a mixture thereof, and n is an integer of 1 to 20.
A production method of a highly crystalline graphitized carbon support, the production method comprising the steps of:
- applying a stepwise heat treatment process to carbon particles to form a highly crystalline graphitized layer;
- and
- coupling reacting the highly crystalline graphitized layer with a functional group-substituted diazonium salt to introduce an organic functional group into the highly crystalline graphitized layer.
