Abstract

The TiO₂(P25)-supported Pt catalyst has drawn significant interest from researchers due to its high activity. Analysis of the origin of this high catalytic activity must address the heterogeneity of the catalyst, since TiO₂(P25) comprises both anatase and rutile phases. Thus, in this study, we demonstrate a simple method for determining the ratio of Pt particles on anatase and rutile by X-ray diffraction and transmission electron microscopy, without employing special equipment. Such a cost-effective method for determining the Pt distribution will accelerate research into the use of TiO₂(P25) as a catalyst support.
