Abstract
In order to investigate the influence of particle morphology on the catalytic activity of supported Pt model catalyst, platinum nanoparticles (NPs) with different morphologies were synthesized by a chemical method and loaded onto SiO2 to give well-defined supported catalysts. CO oxidation was used as the probe to investigate the catalytic activities of these Pt/SiO2 model catalysts. X-ray fluorescence, X-ray photoelectron spectroscopy, diffuse reflectance Fourier transform infrared spectroscopy, and transmission electron microscopy characterization demonstrated that the different activities of these Pt/SiO2 catalysts were due to different crystal surfaces, which strongly influenced the adsorption and oxidation of CO on the Pt NPs.
