摘要：
To support Pt on finely dispersed SiO2 or TiO2/Ti structures obtained via the plasma-electrochemical technique, the extraction-pyrolytic method was used. By means of scanning electron microscopy and X-ray spectral analysis, it was shown that the oxide compositions contain up to 3.5 wt % of Pt. The resulting compositions, Pt/SiO2 and Pt/TiO2/Ti, were tested as catalysts for CO conversion. In the first case, the complete conversion of CO can be reached at 250A degrees C, while in the second case it can be reached at 300A degrees C.
