Our observations indicate that cations in the electrolyte do not affect proton reduction at low potentials. However, an increase in cation concentration significantly enhances water reduction. Simultaneously, we identify a non-negligible migration current under mass transport limited conditions in electrolytes with low cation concentration. To separate migration effects from specific cation-promotion effects on HER, we carried out further experiments with electrolytes with mixtures of Li⁺ and K⁺ cations. Our results show that, adding strongly hydrated cations (Li⁺) to a K⁺-containing electrolyte leads to a less negative onset potential of water reduction. Interfacial pH measurements reveal a same interfacial pH at the platinum electrode in pH 3 in the presence of 80 mM LiClO₄ and KClO₄, respectively, at potentials where water reduction occurs. Based on these results, we suggest that under the current conditions, the strongly hydrated cations (Li⁺) promote water dissociation on the Pt electrode more favorably in comparison with the more weakly hydrated cations (K⁺), and that this promotion is not related to a local pH effect.</p></div>","PeriodicalId":304,"journal":{"name":"Electrochemistry Communications","volume":"166 ","pages":"Article 107784"},"PeriodicalIF":4.7,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1388248124001279/pdfft?md5=9b10761716ee3d3b836bf23ec03236ce&pid=1-s2.0-S1388248124001279-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141839399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings contribute valuable insights into the application of induced overpotential in enhancing the deoxidation of low-grade titanium scrap through molten salt electrolysis.
