Research Abstract

In this research, we successfully made to form Pt clusters on multi-wall nanotubes (MWNT) by a new size control method from single atoms to 5 nm clusters and discussed unique characteristics associated with electrocatalytical activity of Pt clusters. By X-ray measurements; X-ray photoelectron spectroscopy (XPS), in-situ powder X-ray diffractometry (XRD), in-situ or ex-situ XANES and EXAFS, using synchrotron radiation on samples prepared from the reduction of a Pt precursor on thiolated MWNT, clusters around 2nm and the dynamical fluctuations of these crystalline structures of during formation processes were investigated, particularly focusing on a disorder-to-crystalline transformation in. From these results, it was demonstrated the formation processes of Pt clusters on MWNT, which is quite consistent with the simulation of these behaviors obtained by the first principle DFT calculations.
