| 요약 | 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 |
| 요약 | 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 |
| 요약 | 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 |
| 요약 | 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 |
| 요약 | Pt and Pt deposited onto SrTiO3 nanopolyhedra were investigated by HREM to determine the stable Winterbottom construction. |
| 요약 | 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 |
| 요약 | 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 |
