520 ▼a The atomic surfaces structures of shape-controlled oxide supports prepared hydrothermally result in nanocrystals for use as model catalysts to bridge the "materials gap" from studies on single crystals. SrTiO3 (001), (110), and BaTiO3 (001) surf
520 ▼a The Wulff shape of SrTiO3 was determined to be an octadecahedron with six {100} facets and twelve {110} facets. TEM measurements of the faceting ratios h110:h100 were found to agree well with surface energy ratios gamma110 :gamma100 derived fro
520 ▼a Using aberration-corrected HREM, the surface structure of {110}-faceted SrTiO3 nanoparticles synthesized solvothermally using glycerol as the surfactant yielded (n x 1) reconstructions with n=3 or 4. These structures are titania-rich and contain
520 ▼a Aberration-corrected HREM investigation of SrTiO3 nanocuboids made using caprylic acid, ethanol, and also BaTiO3 nanocuboids revealed that the (001) surfaces for all these nanoparticles are terminated with a TiO2 double layer. These results are
520 ▼a Pt and Pt deposited onto SrTiO3 nanopolyhedra were investigated by HREM to determine the stable Winterbottom construction.
520 ▼a The supported Pd particles were found to be predominantly multiply twinned particles while Pt particles were predominantly single crystals. The effects of sub-nanometer atomic layer deposition of films of titania and alumina are compared for the
520 ▼a Pt-SrTiO3 (110) catalyst samples prepared by ALD onto SrTiO 3 dodecahedra are compared with Pt-TiO2 catalysts prepared by ALD onto commercially purchased anatase TiO2. Catalytic testing of the CO oxidation reaction indicate that the turnover fre
