Herein, we studied the reduction of H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> at nickel and at nickel-rare earth (RE = Ce, Sm, Dy) alloys containing 5 and 10 at.% of RE metal. The alloys were prepared by arc melting, starting from the stoichiometric amounts of the two parent metals, and analyzed by X-ray diffraction and scanning electron microscopy coupled with energy-dispersive spectroscopy. The electrochemical characterization was carried out by voltammetry and chronoamperometry measurements in alkaline media. Ni<jats:sub>0.95<\/jats:sub>Ce<jats:sub>0.05<\/jats:sub> alloy exhibited the highest catalytic activity for H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> reduction reaction, with a number of exchanged electrons of 1.7. Additionally, activation energies were estimated according to Arrhenius equation.<\/jats:p>","DOI":"10.1149\/07225.0031ecst","type":"journal-article","created":{"date-parts":[[2016,9,22]],"date-time":"2016-09-22T02:39:07Z","timestamp":1474511947000},"page":"31-40","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Nickel-Rare Earth (RE = Ce, Sm, Dy) Electrodes for H<sub>2<\/sub>O<sub>2<\/sub> Reduction in Fuel Cells"],"prefix":"10.1149","volume":"72","author":[{"given":"Diogo M.F.","family":"Santos","sequence":"first","affiliation":[]},{"given":"David","family":"Cardoso","sequence":"additional","affiliation":[]},{"given":"Biljana","family":"Sljukic","sequence":"additional","affiliation":[]},{"given":"Cesar A.C.","family":"Sequeira","sequence":"additional","affiliation":[]},{"given":"Daniele","family":"Macci\u00f2","sequence":"additional","affiliation":[]},{"given":"Adriana","family":"Saccone","sequence":"additional","affiliation":[]}],"member":"77","container-title":["ECS Transactions"],"original-title":[],"link":[{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/07225.0031ecst","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/07225.0031ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/07225.0031ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1149\/07225.0031ecst","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/07225.0031ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,1,14]],"date-time":"2022-01-14T02:27:24Z","timestamp":1642127244000},"score":1,"resource":{"primary":{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/07225.0031ecst"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,7,28]]},"references-count":0,"journal-issue":{"issue":"25","published-print":{"date-parts":[[2016,7,28]]}},"URL":"https:\/\/doi.org\/10.1149\/07225.0031ecst","relation":{},"ISSN":["1938-5862","1938-6737"],"issn-type":[{"type":"print","value":"1938-5862"},{"type":"electronic","value":"1938-6737"}],"subject":[],"published":{"date-parts":[[2016,7,28]]},"assertion":[{"value":"Nickel-Rare Earth (RE = Ce, Sm, Dy) Electrodes for H2O2 Reduction in Fuel Cells","name":"article_title","label":"Article Title"},{"value":"ECS Transactions","name":"journal_title","label":"Journal Title"},{"value":"paper","name":"article_type","label":"Article Type"},{"value":"\u00a9 2016 ECS - The Electrochemical Society","name":"copyright_information","label":"Copyright Information"},{"name":"date_received","label":"Date Received","group":{"name":"publication_dates","label":"Publication dates"}},{"name":"date_accepted","label":"Date Accepted","group":{"name":"publication_dates","label":"Publication dates"}},{"name":"date_epub","label":"Online publication date","group":{"name":"publication_dates","label":"Publication dates"}}]}}
