Well-defined Pd particles (mean size of 5\u20137nm) were grown epitaxially on NaCl (001) surfaces and subsequently covered by a layer of amorphous SiO2\u2008(25nm), prepared by reactive deposition of SiO in 10\u22122Pa\u2008O2. The resulting films were exposed to molecular O2 in the temperature range of 373\u2013673K, and the growth of PdO was studied. The formation of a PdO phase starts at 623K and is almost completed at 673K. The high-resolution experiments suggest a topotactic growth of PdO crystallites on top of the original Pd particles. Subsequent reaction of the PdO in 10mbar CO for 15min and thermal decomposition in 1bar He for 1h were also investigated in the temperature range from 373to573K. Reductive treatments in CO up to 493K do not cause a significant change in the PdO structure. The reduction of PdO starts at 503K and is completed at 523K. In contrast, PdO decomposes in 1bar He at around 573K. The mechanism of PdO growth and decay is discussed and compared to results of previous studies on other metals, e.g., on rhodium.<\/jats:p>","DOI":"10.1063\/1.2338028","type":"journal-article","created":{"date-parts":[[2006,9,2]],"date-time":"2006-09-02T05:56:50Z","timestamp":1157176610000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":68,"title":["Growth and decomposition of aligned and ordered PdO nanoparticles"],"prefix":"10.1063","volume":"125","author":[{"given":"Simon","family":"Penner","sequence":"first","affiliation":[{"name":"University of Innsbruck Institute of Physical Chemistry, , Innrain 52a, A-6020 Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Di","family":"Wang","sequence":"additional","affiliation":[{"name":"Fritz-Haber-Institut of the Max-Planck Society Department of Inorganic Chemistry, , Faradayweg 4-6, D-14195 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernd","family":"Jenewein","sequence":"additional","affiliation":[{"name":"University of Innsbruck Institute of Physical Chemistry, , Innrain 52a, A-6020 Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harald","family":"Gabasch","sequence":"additional","affiliation":[{"name":"University of Innsbruck Institute of Physical Chemistry, , Innrain 52a, A-6020 Innsbruck, Austria and Department of Inorganic Chemistry, , Faradayweg 4-6, D-14195 Berlin, Germany"},{"name":"Fritz-Haber-Institut of the Max-Planck Society Institute of Physical Chemistry, , Innrain 52a, A-6020 Innsbruck, Austria and Department of Inorganic Chemistry, , Faradayweg 4-6, D-14195 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernhard","family":"Kl\u00f6tzer","sequence":"additional","affiliation":[{"name":"University of Innsbruck Institute of Physical Chemistry, , Innrain 52a, A-6020 Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Axel","family":"Knop-Gericke","sequence":"additional","affiliation":[{"name":"Fritz-Haber-Institut of the Max-Planck Society Department of Inorganic Chemistry, , Faradayweg 4-6, D-14195 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Schl\u00f6gl","sequence":"additional","affiliation":[{"name":"Fritz-Haber-Institut of the Max-Planck Society Department of Inorganic Chemistry, , Faradayweg 4-6, D-14195 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konrad","family":"Hayek","sequence":"additional","affiliation":[{"name":"University of Innsbruck Institute of Physical Chemistry, , Innrain 52a, A-6020 Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2006,9,1]]},"reference":[{"key":"2023062603583223400_c1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1080\/01614948408078059","volume":"26","year":"1984","journal-title":"Catal.
