They have emerged as potential systems to power portable applications, providing clean energy, and offering good commercial viability. Ethanol is considered one of the most interesting fuels in this field. Herein, platinum-rare earth (Pt-RE) binary alloys (RE = Ce, Sm, Ho, Dy, nominal composition 50 at.% Pt) were produced and studied as anodes for ethanol oxidation reaction (EOR) in alkaline medium. A Pt-Dy alloy with nominal composition 40 at.% Pt was also tested. Their electrocatalytic performance was evaluated by voltammetric and chronoamperometric measurements in 2 M NaOH solution with different ethanol concentrations (0.2\u20130.8 M) in the 25\u201345 \u00b0C temperature range. Several EOR kinetic parameters were determined for the Pt-RE alloys, namely the charge transfer and diffusion coefficients, and the number of exchanged electrons. Charge transfer coefficients ranging from 0.60 to 0.69 and n values as high as 0.7 were obtained for the Pt0.5Sm0.5 electrode. The EOR reaction order at the Pt-RE alloys was found to vary between 0.4 and 0.9. The Pt-RE electrodes displayed superior performance for EOR than bare Pt, with Pt0.5Sm0.5 exhibiting the highest electrocatalytic activity. The improved electrocatalytic activity in all of the evaluated Pt-RE binary alloys suggests a strategy for the solution of the existing anode issues due to the structure-sensitive EOR.<\/jats:p>","DOI":"10.3390\/en13071658","type":"journal-article","created":{"date-parts":[[2020,4,2]],"date-time":"2020-04-02T11:57:14Z","timestamp":1585828634000},"page":"1658","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Ethanol Electrooxidation at Platinum-Rare Earth (RE = Ce, Sm, Ho, Dy) Binary Alloys"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7920-2638","authenticated-orcid":false,"given":"D.M.F.","family":"Santos","sequence":"first","affiliation":[{"name":"CeFEMA, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisbon, Portugal"}]},{"given":"J.R.B.","family":"Louren\u00e7o","sequence":"additional","affiliation":[{"name":"CeFEMA, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4422-0438","authenticated-orcid":false,"given":"D.","family":"Macci\u00f2","sequence":"additional","affiliation":[{"name":"Dipartimento di Ch\u00edmica e Ch\u00edmica Industriale, Universit\u00e1 di Genova, I-16146 Genova, Italy"}]},{"given":"A.","family":"Saccone","sequence":"additional","affiliation":[{"name":"Dipartimento di Ch\u00edmica e Ch\u00edmica Industriale, Universit\u00e1 di Genova, I-16146 Genova, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7556-2858","authenticated-orcid":false,"given":"C.A.C.","family":"Sequeira","sequence":"additional","affiliation":[{"name":"CeFEMA, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0395-8199","authenticated-orcid":false,"given":"J.L.","family":"Figueiredo","sequence":"additional","affiliation":[{"name":"Laboratory of Catalysis and Materials, LSRE-LCM, Faculdade de Engenharia, Universidade do Porto, 4200-465 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"31","DOI":"10.1016\/S0378-7753(01)01069-2","article-title":"Fuel cells for portable applications","volume":"106","author":"Dyer","year":"2002","journal-title":"J.
