Selective oxidation of nitric oxide against nitrite by oxo-iron(IV) porphyrin at an ITO electrode
Electrochemical and spectroelectrochemical experiments at an ITO electrode clarified that O=Fe-IV(4-TMPyP) was formed via 1e(-) + 1H(+) oxidation process of Fe-III(4-TMPyP) in pH 7.4 PBS and the electrogenerated O=Fe-IV(4-TMPyP) selectively reacted with NO to give NO2- as the final product through an electrocatalytic cycle.
