| 抄録: | For fine particles of semiconductive rutile TiO2 supporting ultra-fine particles of Pt which were prepared by decomposing a colloidal organic-Pt complex, the structural aspects of the high photoactivity were examined by high resolution imaging, X-ray mapping by energy dispersive spectroscopy and electron energy-loss spectroscopy. As a result, the Pt particles with nm-sizes were found to grow epitaxially on rutile, which supports an expected mechanism that the photo-excited electrons efficiently transfer from TiO2 to Pt and promote the reduction of O2 to O2 -. |
