1. A bifunctional catalyst for manufacturing a hydrocarbon from carbon dioxide and hydrogen, the bifunctional catalyst comprising:
a carbon composite support including cobalt (Co) and nitrogen (N) atoms forming a coordinate bond with the cobalt; and
metal particles which exhibit a catalytic activity for a Fischer-Tropsch synthesis reaction and which are dispersed on an inner pore surface and/or an outer surface of the carbon composite support, thus simultaneously promoting a reverse water gas shift reaction and the Fischer-Tropsch synthesis reaction,
wherein the carbon composite support includes a structure represented by a following Structural Formula 1:

OG Complex Work Unit Chemistry
in the Structural Formula 1, x is any one integer of 1 to 4, and ‘-*’ is a site connected to a carbon (C) atom in the carbon composite support.
