| 中文摘要 | the use of room-temperature ionic liquids (rtils) as media for electrochemical application is very attractive. in this work, the electrochemical deposition of silver was investigated at a glassy carbon electrode in hydrophobic 1-n-butyl-3-methylimidazolium hexafluorophosphate (bmimpf6) and hydrophilic 1-n-butyl-3-methylimidazolium tetrafluoroborate (bmimbf4) rtils and in kno3 aqueous solution by cyclic voltammetric and potentiostatic transient techniques. the voltammograms showed the presence of reduction and oxidation peaks associated with the deposition and dissolution of silver from agbf4 in both bmimpf6 and bmimbf4, resembling the redox behavior of agno3 in kno3 aqueous solution. a crossover loop was observed in all the cyclic voltammograms of these electrochemical systems, indicating a nucleation process. from the analysis of the experimental current transients, it was shown that the electrochemical deposition process of silver in these media was characteristic of 3d nucleation with diffusion-controlled hemispherical growth, and the silver nucleation closely followed the response predicted for progressive nucleation in bmimpf6 and instantaneous nucleation in kno3 aqueous solution, respectively. |
