| Abstract: | The behavior of platinum electrode were studied by cyclic voltammetry in 1mol/L sulfuric acid solution and 1mol/L sulfuric acid solution containing 10 -3 mol /L benzene. The absorption characters for oxygen, hydrogen, and benzene and the oxidation products on electrode surface have been discussed. The reactive reversibility and oxidation of benzene on electrode process have been investigated. In acid solutions, benzene is absorbed chemically on anode, while physical adsorption occurs on cathode. The control step is irreversible electrochemical activation for oxidation process and subsequent steps are faster. It is suggested that the reaction follows an EC mechanism. |
| Keywords: | cyclic voltammetry platinum electrode adsorption anode oxidation reaction mechanism |
