By means of XPS, the binding energy and the concentration of the surface element were characterized, before and after the catalyst was exposed to CH4 and/or O2 at different temperature (from room temperature to 773 K) and at different amounts with different sequence. It was found that CHx(x=l~3) species were formed over the catalyst closed to CH4 or CH4/O2. For CH3,CH2 and CH species, the C1Sbinding energies were ca. 285.5 eV, 284.5 eV and 283.5 eV, respectively. |
