In such experiments, the oxidized surface is put in contact with the fuel under open circuit conditions, and the evolution of the potential is registered. The open circuit potential (OCP) <jats:italic>vs<\/jats:italic>. time features can then inform on the reactivity of the fuel with the oxidized surface and provide valuable information not only to applications in fuel cells but also to the electrochemical reform of those molecules to produce clean hydrogen. In this paper, we present an experimental investigation of the open circuit interaction between ethanol or 2\u2010propanol with oxidized platinum surfaces. Besides the OCP time traces, we have also employed cyclic voltammetry and fast oxide reduction sweep in the presence of the alcohols. Comparable reaction currents are obtained in the cyclic voltammogram, but the electro\u2010oxidation of 2\u2010propanol sets in at considerably lower overpotentials than that of ethanol. At the high potential region, both the magnitude and the potential of the current peak are nearly identical in both cases. In contrast, under open circuit conditions, the interaction of ethanol with the oxidized platinum surface is more pronounced than that found for 2\u2010propanol, and these results are corroborated by the facile reduction of the platinum oxides along the fast backward sweep for the case of the latter.<\/jats:p>","DOI":"10.1002\/cphc.202400359","type":"journal-article","created":{"date-parts":[[2024,5,9]],"date-time":"2024-05-09T05:31:18Z","timestamp":1715232678000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Open Circuit Interaction Between Ethanol or 2\u2010Propanol and Oxidized Platinum Surfaces"],"prefix":"10.1002","volume":"25","author":[{"given":"Gianluca","family":"Ragassi","sequence":"first","affiliation":[{"name":"S\u00e3o Carlos Institute of Chemistry (IQSC) University of S\u00e3o Paulo (USP)  PO Box 780 13560-970 S\u00e3o Carlos SP Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3181-0076","authenticated-orcid":false,"given":"Elton","family":"Sitta","sequence":"additional","affiliation":[{"name":"Department of Chemistry Federal University of Sao Carlos (UFSCar)  Sao Carlos Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changwei","family":"Pan","sequence":"additional","affiliation":[{"name":"College of Chemical Engineering China University of Mining and Technology  Xuzhou 221116 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingyu","family":"Gao","sequence":"additional","affiliation":[{"name":"College of Chemical Engineering China University of Mining and Technology  Xuzhou 221116 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6237-6068","authenticated-orcid":false,"given":"Hamilton","family":"Varela","sequence":"additional","affiliation":[{"name":"S\u00e3o Carlos Institute of Chemistry (IQSC) University of S\u00e3o Paulo (USP)  PO Box 780 13560-970 S\u00e3o Carlos SP Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,6,20]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"crossref","unstructured":"H.
