| Abstract | Uniform one-dimensional Pt nanowires prepared by etching FePt nanowires precursor exhibit high conversion yield and selectivity in aromatic azo compounds reaction compared to the other Pt-based catalysts, such as Pt nanorods and Pt nanopartides. The X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) were employed to investigate the electronic structure and short-range local environment of the three Pt nanostructures, revealing that the high density of unsaturated coordinated atoms in the short-range local structure of Pt nanowires contribute to the superior catalytic performance of the nanowires. Furthermore, the quasi in situ XANES was carried out to monitor the electronic structural evolution of the Pt nanowires during the different stages in the whole reaction process, which further clarify the Pt OH involved catalytic reaction mechanism. This work delineates the correlation between catalytic performance and structural sensitivity of Pt-based catalysts investigated by X-ray absorption spectroscopy. |
