Abstract: Provided is a device for removing nitrogen oxide, the device including an inflow path for gas containing nitrogen oxide; and a reversible metal complex compound coming into contact with the gas containing nitrogen oxide which is introduced through the inflow path, wherein the reversible metal complex compound includes a central metal ion reacting and binding with nitrogen oxide; and a ligand coordinating with the central metal ion, wherein when the central metal ion is oxidized, the bound nitrogen oxide is separated, and the oxidized central metal ion is reduced to recombine with nitrogen oxide.
