| Abstract | The influence of the nature of TiO2 support and platinum salt precursors on the state and CO catalysis oxidation activity of supported platinum on TiO2 was investigated in this paper. Variations of the support TiO2 and platinum precursor significantly influenced the CO catalytic oxidation activity of platinum. X-ray diffraction, transmission electron microscopy, in situ diffuse reflectance infrared Fourier transform spectroscopy, and X-ray absorption fine structure analysis of the Pt/TiO2 catalysts were carried out to correlate the relationship between the state of platinum and CO catalysis activity. The dispersion of Pt on different TiO2 surfaces using diammine dinitritoplatinum as precursor decreased in the following order: Pt/rutile TiO2 (rutile phase TiO2 synthesized by hydrothermal method), Pt/anatase TiO2 (by sol-gel method), and Pt/rutile TiO2 (by sol-gel method). CO catalysis activity of Pt supported on different TiO2 decreased with the decrease of Pt dispersion. Chloroplatinic acid played an important role in the formation of electron-rich platinum with lower Pt-Pt and Pt-O coordination number on rutile TiO2 (hydrothermal) surface compared to that using diammine dinitritoplatinum as a metal salt precursor, which contributed to the highest CO catalysis oxidation activity. |
