For both substrates the saturated C-H bonds are preferentially activated over the unsaturated ones. The catalyst seems fairly stable towards leaching phenomena. The liquid-phase oxidation catalysis may be associated with the Ce3+\/Ce4+ inter-conversion in the one-electron redox processes mediating the formation of tert-butyl-(per)oxy radicals. CeNR is very effective in H2O2 disproportionation. Pre-treatment of CeNR with H2O2 or t-BuOOH prior to the catalytic reaction enhances the reaction rate of PhEt with t-BuOOH in comparison to CeNR. Textural characterization and spectroscopic studies suggest that catalytic activation is associated to defect sites.<\/jats:p>","DOI":"10.3390\/molecules15020747","type":"journal-article","created":{"date-parts":[[2010,2,2]],"date-time":"2010-02-02T11:18:13Z","timestamp":1265109493000},"page":"747-765","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Catalytic Performance of Ceria Nanorods in Liquid-Phase Oxidations of Hydrocarbons with tert-Butyl Hydroperoxide"],"prefix":"10.3390","volume":"15","author":[{"given":"Andreia  G.","family":"Macedo","sequence":"first","affiliation":[{"name":"Department of Physics, CICECO, University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"Department of Chemistry, CICECO, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"S\u00edlvia E.
