Abstract:
The catalytic activity of 3 different C-supported Pt-Sn catalysts for the anodic oxidn. of hydrogen, CO, and H2/CO mixts. is correlated with the bimetallic microstructure established in Part I [V. Radmilovic, T. J. Richardson, S. J. Chen, P. N. Ross, Jr. (2005)] of this study. These catalysts differ primarily by having differing amts. of Pt, Pt3Sn, PtSn, and SnO2 phase nanoparticles distributed on the C support. Further surface chem. characterization of the Pt3Sn nanoparticles is provided by com...     »
