| Outline of Final Research Achievements |
The purpose of this study is to fabricate highly active catalysts for low temperature oxidation based on the formation of effective boundary between noble metal and metal oxide. Pt-FeOx/γ-Al2O3 with our original preparation method, the water-pretreatment, was employed as a base catalyst system. From structural studies, the Fe moiety in the FeOx/γ-Al2O3 samples with low Fe loadings (below 9wt%) were suggested to take the form in which an isolated iron-oxide monomers are supported on theγ-Alumina surface. Catalytic CO oxidation below 120°C was maximized at the Fe content where Fe to Pt molar ratio was 1, whereas above 120°C the conversion increased monotonically with Fe content. In the case of propane oxidation, Fe contents lowered the oxidation temperature. This is probably due to the promotion of C-H dissociative adsorption of propane on Pt during the oxidation reaction.
