The trimetallic nanoparticles showed high catalytic activity towards FA oxidation above 0.1 V vs Ag/AgCl as compared to SiO2@Au/Pd and SiO2@Au/Pt and the activity depends on the Pt coverage: the higher the Pt coverage, the lower the FA oxidation activity. It was also observed that CO and PDI adsorption depends on the exposed facet of the Au nanocrystals as suggested by the different C-O and C-N stretching frequencies. The different facets of gold nanocrystals also exhibited high facet-dependent SERS activity and can be employed as substrates in other studies. The current studies augmented insight into electrocatalysis of FA oxidation and demonstrate the potential for multi-metallic nanoparticles in the design of catalysts for electrocatalysis. 2016-01-07 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1451993102 http://rave.ohiolink.edu/etdc/view?acc_num=miami1451993102 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
