High-angle annular dark field (HAADF) scanning transmission electron microscopy (STEM) and energy-dispersive X-ray (EDX) elemental mapping techniques were used to analyze the morphology and composition of the particles at the nanoscale. The particles show similar atomic compositions for both treated samples but different elemental distribution on the surface of the nanooctahedra. X-ray photoelectron spectroscopy (XPS) analysis confirmed different surface compositions and the presence of different oxidation states species at the outer part of the nanoparticles. In addition, we compare characteristic voltammetric profiles of these nanocatalysts when immersed in three different aqueous supporting electrolytes (H2SO4, HClO4 and NaOH). The behavior of the bimetallic nanoparticles towards adsorbed CO oxidation has been analyzed and compared with that observed after surface disordering of the same catalysts. The electrocatalytic activity of these nanoparticles has been also tested for the electroreduction of oxygen showing high specific and mass activity and better catalytic performance than pure Pt shaped nanoparticles. The different treatments applied to the surface of the nanocatalysts have led to remarkably different catalytic responses, pointing out the outstanding importance of the control of the surface of the alloyed shape-selected nanoparticles after their synthesis and before their use as electrocatalysts. 000825374 536__ $$0G:(DE-HGF)POF3-143$$a143 - Controlling Configuration-Based Phenomena (POF3-143)$$cPOF3-143$$fPOF III$$x0 000825374 588__ $$aDataset connected to CrossRef 000825374 7001_ $$0P:(DE-HGF)0$$aSolla-Gullón, José$$b1 000825374 7001_ $$0P:(DE-Juel1)166087$$aGocyla, Martin$$b2 000825374 7001_ $$0P:(DE-Juel1)130695$$aHeggen, Marc$$b3 000825374 7001_ $$0P:(DE-Juel1)144121$$aDunin-Borkowski, Rafal$$b4 000825374 7001_ $$0P:(DE-HGF)0$$aStrasser, Peter$$b5 000825374 7001_ $$0P:(DE-HGF)0$$aHerrero, Enrique$$b6 000825374 7001_ $$0P:(DE-HGF)0$$aFeliu, Juan M.$$b7$$eCorresponding author 000825374 773__ $$0PERI:(DE-600)2648700-7$$a10.1016/j.nanoen.2016.07.024$$gVol. 27, p. 390 - 401$$p390 - 401$$tNano energy$$v27$$x2211-2855$$y2016 000825374 8564_ $$uhttps://juser.fz-juelich.de/record/825374/files/1-s2.0-S2211285516302646-main.pdf$$yRestricted 000825374 8564_ $$uhttps://juser.fz-juelich.de/record/825374/files/1-s2.0-S2211285516302646-main.gif?subformat=icon$$xicon$$yRestricted 000825374 8564_ $$uhttps://juser.fz-juelich.de/record/825374/files/1-s2.0-S2211285516302646-main.jpg?subformat=icon-1440$$xicon-1440$$yRestricted 000825374 8564_ $$uhttps://juser.fz-juelich.de/record/825374/files/1-s2.0-S2211285516302646-main.jpg?subformat=icon-180$$xicon-180$$yRestricted 000825374 8564_ $$uhttps://juser.fz-juelich.de/record/825374/files/1-s2.0-S2211285516302646-main.jpg?subformat=icon-640$$xicon-640$$yRestricted 000825374 8564_ $$uhttps://juser.fz-juelich.de/record/825374/files/1-s2.0-S2211285516302646-main.pdf?subformat=pdfa$$xpdfa$$yRestricted 000825374 909CO $$ooai:juser.fz-juelich.de:825374$$pVDB 000825374 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)166087$$aForschungszentrum Jülich$$b2$$kFZJ 000825374 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130695$$aForschungszentrum Jülich$$b3$$kFZJ 000825374 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)144121$$aForschungszentrum Jülich$$b4$$kFZJ 000825374 9131_ $$0G:(DE-HGF)POF3-143$$1G:(DE-HGF)POF3-140$$2G:(DE-HGF)POF3-100$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bEnergie$$lFuture Information Technology - Fundamentals, Novel Concepts and Energy Efficiency (FIT)$$vControlling Configuration-Based Phenomena$$x0 000825374 9141_ $$y2016 000825374 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000825374 915__ $$0StatID:(DE-HGF)1160$$2StatID$$aDBCoverage$$bCurrent Contents - Engineering, Computing and Technology 000825374 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bNANO ENERGY : 2015 000825374 915__ $$0StatID:(DE-HGF)9910$$2StatID$$aIF >= 10$$bNANO ENERGY : 2015 000825374 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000825374 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000825374 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000825374 915__ $$0StatID:(DE-HGF)0550$$2StatID$$aNo Authors Fulltext 000825374 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000825374 920__ $$lyes 000825374 9201_ $$0I:(DE-Juel1)PGI-5-20110106$$kPGI-5$$lMikrostrukturforschung$$x0 000825374 980__ $$ajournal 000825374 980__ $$aVDB 000825374 980__ $$aUNRESTRICTED 000825374 980__ $$aI:(DE-Juel1)PGI-5-20110106 000825374 981__ $$aI:(DE-Juel1)ER-C-1-20170209
