邻碘苯甲酸电还原脱碘的原位红外光谱研究
In Situ Fourier Infrared Spectroscopy Studies on Electrochemical Deiodination Reaction of 2-Iodobenzoic Acid
摘要
Abstract
Electrochemical reduction of 2-iodobcnzoic acid (OIBA) in NaOH solution was investigated by cyclic voltammetry. To compared with Pt and Ti electrodes, Ag and Cu electrodes exhibited good electrocatalytic activity for the electroreduction of OIBA, and the electrochemical deiodination reaction could take place at more positive potentials on Ag and Cu electrodes. The study on the mechanism of OIBA by in situ FT1R spectroscopy showed that there were different between Ag and Cu electrodes during electrocatalytic reductive deiodination reaction of OIBA at the potentials positive than -800 mV, the absorption state of R ...l...Ag was formed on Ag electrode initially, while OIBA existed as negative ions on Cu electrode. Then OIBA was processed by a series of deiodination and hydrogena-tion reactions at more negative potentials at Ag and Cu electrodes, and benzoic acid was obtained finally.关键词
