Effect of H2O2 on Pt electrode dissolution in H2SO4 solution based on electrochemical quartz crystal microbalance study
The effect of H2O2 on the Pt dissolution in 0.5 mol dm−3 H2SO4 was investigated using an electrochemical quartz crystal microbalance (EQCM). For the potential cycling at 50 mV s−1, the Pt weight irreversibly decreases in a N2 atmosphere with H2O2, while only a negligible Pt weight-loss is observed i...

| description | The effect of H2O2 on the Pt dissolution in 0.5 mol dm−3 H2SO4 was investigated using an electrochemical quartz crystal microbalance (EQCM). For the potential cycling at 50 mV s−1, the Pt weight irreversibly decreases in a N2 atmosphere with H2O2, while only a negligible Pt weight-loss is observed in the N2 and O2 atmospheres without H2O2. The EQCM data measured by the potential step showed that the Pt dissolution in the presence of H2O2 depends on the electrode potential and the H2O2 concentration. For the stationary electrolysis, the Pt dissolution occurs at 0.61–1.06 and 1.06–1.36 V vs. RHE. It should be noted that the Pt dissolution phenomenon in the presence of H2O2 is also affected by the potential scanning time. Based on these results, H2O2 is considered not only to contribute to the formation of Pt-oxide causing the cathodic Pt dissolution, but also to participate in the anodic Pt dissolution and the chemical Pt dissolution.
► The Pt dissolution is accelerated by potential scanning in H2O2-containing H2SO4. ► The Pt dissolution in the presence of H2O2 depends on the electrode potential and the H2O2 amount. ► The potential scanning time affects the Pt dissolution phenomenon in H2SO4 containing H2O2. ► H2O2 contributes to the Pt-oxide formation causing the cathodic Pt dissolution. ► H2O2 also participates in the anodic Pt dissolution and the chemical Pt dissolution. |
