The carbon support surface was previously activated with a sensitizing and activating pre-treatment. The as-prepared PdSn catalyst was then heat treated at 300 \u00baC in H<jats:sub>2<\/jats:sub>\/N<jats:sub>2<\/jats:sub> (3vol.% H<jats:sub>2<\/jats:sub>). The PdSn catalysts were characterized by SEM\/EDX, XRD and TEM before and after the heat treatment. The electrochemical activity towards ORR was examined by cyclic and rotating disk electrode measurements and compared with that of Pd. The ORR catalytic activity of PdSn heat treated catalyst was about 25 and 4 times higher than that of as-prepared and Pd catalyst, respectively. Accelerated stability test (AST) by repetitive potential cycling indicated that PdSn heat treated was very stable in electrochemical environment. <\/jats:p>","DOI":"10.1149\/06403.0097ecst","type":"journal-article","created":{"date-parts":[[2014,9,30]],"date-time":"2014-09-30T16:49:56Z","timestamp":1412095796000},"page":"97-106","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Improving the Activity and Stability of PdSn Catalyst for Oxygen Reduction by Heat Treatment"],"prefix":"10.1149","volume":"64","author":[{"given":"S\u00f3nia","family":"Salom\u00e9","sequence":"first","affiliation":[]},{"given":"M.C.","family":"Oliveira","sequence":"additional","affiliation":[]},{"given":"Oumarou","family":"Savadogo","sequence":"additional","affiliation":[]},{"given":"Rosa","family":"Rego","sequence":"additional","affiliation":[]}],"member":"77","container-title":["ECS Transactions"],"original-title":[],"link":[{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/06403.0097ecst","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/06403.0097ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/06403.0097ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1149\/06403.0097ecst","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"},{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/06403.0097ecst\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,2,8]],"date-time":"2022-02-08T00:33:50Z","timestamp":1644280430000},"score":1,"resource":{"primary":{"URL":"https:\/\/iopscience.iop.org\/article\/10.1149\/06403.0097ecst"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,8,18]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2014,8,18]]}},"URL":"https:\/\/doi.org\/10.1149\/06403.0097ecst","relation":{},"ISSN":["1938-5862","1938-6737"],"issn-type":[{"type":"print","value":"1938-5862"},{"type":"electronic","value":"1938-6737"}],"subject":[],"published":{"date-parts":[[2014,8,18]]},"assertion":[{"value":"Improving the Activity and Stability of PdSn Catalyst for Oxygen Reduction by Heat Treatment","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 2014 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"}}]}}
