The photocatalytic oxidation of CO on Pd(2%)/TiO2 was investigated. It was found that CO oxidation activity on Pd/TiO2 was greatly enhanced if illuminated with UV light(λ=365 nm) as compared with that in the dark(the ratio of the above two rate constants is ca. 15). But on bare TiO2 no CO oxidation reaction was observed both in the dark and under UV light illumination. The photocatalytic enhancement of CO on Pd/TiO2 could be elucidated by the increase of surface concentration of oxygen atoms (or O-) on Pd and the spillover of oxygen atoms from Pd to TiO2.

Keywords: CO oxidation   Pd(2%)/TiO2   Oxygen atom   Photocatalytic enhancement   Spillover
