Claim 5:
6. A method of manufacturing a bifunctional catalyst for manufacturing a hydrocarbon from carbon dioxide and hydrogen to simultaneously promote a reverse water gas shift reaction and a Fischer-Tropsch synthesis reaction, the method comprising:
(a) forming a mixture of a cobalt precursor including cobalt (Co), nitrogen (N) atoms forming a coordinate bond with the cobalt, and carbon (C) atoms forming a covalent bond with the nitrogen atoms, and a porous silica template;
(b) pyrolyzing the mixture;
(c) removing the silica template through acid treatment of the pyrolyzed mixture to manufacture a porous carbon composite support; and
(d) carrying a precursor of metal particles having a catalytic activity for the Fischer-Tropsch reaction in the porous carbon composite support in step (c).
