The CeO2 support was prepared by calcining electrospun polymer nanocomposite fibers with a high Ce content; then gold nanoparticles were either synthesized in situ or deposited from a suspension. The prepared catalysts were used in the preferential oxidation of CO in a hydrogen-rich stream. The catalysts prepared by deposition of preformed gold nanoparticles were less stable and underwent sintering due to a weaker nanoparticle–support interaction. In contrast, the catalysts with Au nanoparticles synthesized in situ were active (90% conversion and 46% selectivity) and stable. The fiber-shaped catalyst was able to give maximum reactant access at a much lower pressure drop than catalyst in powder form.2015http://zaguan.unizar.es/record/5614910.1016/j.jcat.2015.06.011http://zaguan.unizar.es/record/56149oai:zaguan.unizar.es:56149info:eu-repo/grantAgreement/ES/DGA/B008/12info:eu-repo/grantAgreement/EUR/ERC/HECTOR Advanced Grant-267626JOURNAL OF CATALYSIS 329 (2015), 479-489by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
