The kinetic peculiarities of CO oxidation on WO3 promoted with Pt or Pd were studied. In the region of low catalyst activity (the degree of CO conversion below 20%), the reaction was found to be zero-order in CO and first-order in oxygen. In the high-activity region (CO conversion above 95%), the reaction order was first with respect to CO and zeroth with respect to oxygen. Hysteresis phenomena were observed for the r - c (O-2) and r - c (CO) dependences at certain temperatures. A reaction scheme combining the heterogeneous and heterogeneous-homogeneous mechanisms was suggested.
