The Effect of Appending of I^-，Fe²⁺ and MnO₄^- to the Electro-Oxidation of Methanol on Platinum Electrode

Abstract:

Three kinds of ions (I^-、Fe²⁺and MnO₄^-) were appended into the methanol aqueous solution respectively as an additive and the Cyclic voltammograms of the aqueous solutions were studied. The results showed that Fe²⁺ had obvious promotion effect for electro-oxidation of methanol and could improve the methanol anodic oxidation current by 85 percent. The promotion effect of the thulium Ions were related with the electronic distribution of these elements and their adsorption on the Pt electrode surface. I^- and MnO₄^- could facilitate the electro-oxidation of methanol at different extent.
