Ammonia is expected as a hydrogen carrier in realizing a hydrogen society. In this study, we calculated the catalyst structure which can synthesize ammonia with less energy by semiempirical molecular orbital calculations with PM7 Hamiltonian. It was clarified that two protons are bonded to N_{2}, only when Os, Mo, or Fe is used as an active site. Also, activation enthalpy is in the order of W < Fe < Ru, therefore, it was concluded that an iron atom is a promising candidate for the active center of ammonia synthesis catalysts. A Fe-coordinated carbon catalyst was synthesized by the immersing the nitrogen-doped Ketjenblack into a Fe(III) aqueous solution, and electrochemical nitrogen reduction reactions using the catalysts were studied using a half cell with a three-phase interface. As a result, it was confirmed that the amount of ammonia produced by the Fe-coordinated carbon catalyst is larger than that by the non-coordinated carbon catalyst, however, Faraday efficiency and energy conversion efficiency decrease due to the enhancement of proton reduction reaction. |
