Claim 10:
11. 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 including a cobalt (Co) precursor and an organic compound containing nitrogen (N);
(b) pyrolyzing the mixture of step (a) in one or more gas atmospheres selected from the group consisting of gases having nitrogen as an element, including nitrogen, ammonia, or acetonitrile, inert gases including helium or argon, and hydrogen;
(c) an acid washing step of washing the pyrolyzed mixture with an acid; and
(d) carrying a precursor of metal particles having a catalytic activity for the Fischer-Tropsch reaction in a porous carbon composite support obtained in step (c),
wherein a porous silica template is further added in the step (a) to form a mixture, and the step (c) is a step of removing the silica template through acid treatment of the pyrolyzed mixture.
