Abstract: Disclosed are an electrochemical hybrid catalyst that has a configuration in which two species of single atomic metals, that is, nickel (Ni) and iron (Fe), each bonded to (coordinated with) nitrogen in a nitrogen-doped carbon nanostructure, are adjacent to each other and are indirectly linked via nitrogen to form a catalyst site or an active site and thus exhibits high carbon monoxide selectivity and current density at a low overpotential during reduction reaction for converting carbon dioxide into carbon monoxide, and a carbon dioxide conversion system using the same.
