Effect of the Morphology of Pt Nanoparticles of Supported Pt Model Catalysts on CO Oxidation
چکیده انگلیسی

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.
