| 摘要 | Spherular-Co3O4 particles were synthesized on graphite electrode surface by ammonia-evaporation-induction. Its electrooxidation catalytic behavior for sulfide ions in an alkaline solution was investigated by electrochemical measurements such as potentiodynamic scanning and potentiostatic polarization. We found that high catalytic activity and the highest current density of 580 mA.cm(-2) were obtained at -0.40 V. In addition, its catalytic performance was stable during potentiostatic polarization. Electrochemical impedance spectroscopy (EIS) indicated a low charge transfer resistance, which explained the high catalytic activity from the viewpoint of electrochemical kinetics. |
