Universidad de Zaragoza Electrospun Au/CeO2 nanofibers: A highly accessible low-pressure drop catalyst for preferential CO oxidation 2015 Access copy available to the general public Unrestricted Au/CeO2 catalysts shaped as nanofibers were obtained by supporting Au nanoparticles (ca. 3 nm) on CeO2 nanofibers of around 200 nm diameter. 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. info:eu-repo/grantAgreement/EUR/ERC/HECTOR-267626 info:eu-repo/grantAgreement/ES/DGA/B008-12 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 7.354 2015 ENGINEERING, CHEMICAL 4 / 135 = 0.03 2015 Q1 T1 CHEMISTRY, PHYSICAL 20 / 144 = 0.139 2015 Q1 T1 2.668 2015 Physical and Theoretical Chemistry 2015 Q1 Catalysis 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0003-3363-2912 Navascues, N.
