The hydrogen peroxide reduction reaction (HPRR) on Pt(111) has been studied for the first time in acid to neutral pH values in the absence of anion specific adsorption using the HMRDE configuration. The onset for the reduction is ca. 0.95 V (RHE) for the Pt(111), irrespective of the pH value. At more negative potential values, the reduction is inhibited. It has been found that the diminution of the activity on Pt(111) occurs at the same potential value in the SHE scale for the different pH values. This indicates that this deactivation is not dependent on the hydrogen adsorption process, as has been previously suggested. However, it appears to be related to the interface water reorganization and the potential of zero free charge of the metal surface. In addition, studies in alkaline conditions suggest that the presence of adsorbed OH species promotes the total conversion of hydrogen peroxide to water.

使用HMRDE配置，在不存在阴离子特异性吸附的情况下，首次在酸性至中性pH值下对Pt（111）上的过氧化氢还原反应（HPRR）进行了研究。减少的开始时间是大约。Pt（111）的pH值为0.95 V（RHE），与pH值无关。在更多的负电势值处，降低被抑制。已经发现，对于不同的pH值，Pt（111）上活性的降低在SHE标度中以相同的电位值发生。这表明该失活不依赖于氢吸附过程，如先前所建议的。然而，这似乎与界面水的重组和金属表面的零自由电荷的潜力有关。此外，
