| Abstract: | In a three-electrode system, dimethylformamide (DMF) and tetrabutyl ammoniumperchlorate (TBAP) used as solvent and supporting electrolyte, Pt micro-disk as working electrode, Pt plate as auxiliary electrode, saturated calomel electrode as reference electrode, the electrochemical behavior of nitrobenzene were studied by mean of cyclic voltammetry. The effects of scan rate and reactant concentration on electrochemical characteristics of nitrobenzene were investigated systematically. It was shown that the ArNO2/ArNO[rad]-2 redox reaction of nitrobenzene on Pt micro-disk electrode was a reversible process with one transfer electron. The control step in this electrochemical process was attributed to the diffusion of nitrobenzene or its electrochemical reductive product. |
