摘要

The Pt/V2O5 and Pd/V2O5 systems formed upon hydrogen reduction have catalytic activity in the oxidation of carbon monoxide exceeding the activity of Pt/Al2O3 and Pd/Al2O3. The transition from the low-activity to high-activity state on the Pt/V2O5 and Pd/V2O5 catalysts is characterized by temperature hysteresis and change in the kinetic equation. X-ray phase analysis (XPA), X-ray photoelectron spectroscopy (XPES), and X-ray spectral microanalysis were used to establish that prior reduction of V2O5 by hydrogen gives VO2, V6O_(13), a-H_xV2O5, andb-H_xV2O5, which facilitates the formation of an active catalyst surface.
