石油学会 年会（研究発表会）

In spite of a large volume of previous studies, the nature of the active sites and the reaction mechanisms governing catalytic reactions are not known in detail. This is primarily because the synthesis of catalysts by traditional methods produces a wide distribution of metal particle sizes and compositions, impeding the accurate assessment on the nature of the surface, the active sites, and the catalytic behavior. This presentation will demonstrate the new synthetic route developed to prepare well-defined catalysts to achieve an effective link between characterizations and reactivity.
