Abstract
The present disclosure relates to a bifunctional catalyst for manufacturing a hydrocarbon from carbon dioxide and hydrogen. The bifunctional catalyst includes a carbon composite 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 the inner pore surface and/or the outer surface of the carbon composite support, thus simultaneously promoting a reverse water gas shift reaction and the Fischer-Tropsch synthesis reaction.
