摘要:	摘要： Bimetallic nanostructured core-shell structures are commonly used as catalysts in a wide variety of reactions. We surmised that the addition of an additional metal would potentially allow catalytic tailoring with the possibility of an increase in activity. Here a tri-metallic catalytic structure, consisting of clustered catalytic Pt on the surface of a Pd shell supported on a rod shaped Au core was fabricated. The significance of the additional metallic component is shown by comparative electrochemically active surface area (ECSA) analysis results for the trimetallic Aurod-Pdshell-Ptcluster, bimetallic Aurod-Ptcluster and monometallic JM-Pt (used as a reference), which have respective ECSA values (cm2/mgPt) of 1883.0, 1371.7 and 879. The potential utility of the trimetallic catalysts was shown in a hydrogen peroxide sensing protocol, which showed the catalyst to have a sensitivity of 604 ìA/mMcm2 within a linear range of 0.0013–6.191 mM. 其他題名： Biosensors (Basel) 出版者： Switzerland: MDPI AG 出版日期： 2014-12-01 出處： Biosensors (Basel), 2014-12, Vol.4 (4), p.461-471 資源來源： Publicly Available Content Database 版權： Copyright MDPI AG 2014 版權： 2014 by the authors; licensee MDPI, Basel, Switzerland. 2014 識別號： ISSN: 2079-6374 識別號： EISSN: 2079-6374 識別號： DOI: 10.3390/bios4040461 識別號： PMID: 25587434
