Studies on Electrochemical Hydrodeiodination Mechanism of 2-Iodobenzoic Acid on Cu Electrode by in-Situ FTIR Spectroscopy


Article Preview

Abstract. Electrochemical hydrodeiodination of 2-iodobenzoic acid in NaOH solution was investigated using cyclic voltammetry. Compared with Ti and Pt electrodes, Cu electrode exhibited good electrocatalyitc activity for the electroreduction of 2-iodobenzoic acid. In situ FTIR results suggested that the mechanism of the reaction was electrochemical hydrodeiodination process. 2-Iodobenzoic acid was electroreduced to its free radical ion after receiving an electron firstly. Then the free radical ion was further deiodinated to produce benzoic acid free radical at more negative potential. After receiving another electron and proton, benzoic acid was obtained.
