Abstract：

A　visible　light　(490-780　nm)　was　introduced　into　the　process　of　oxidizing　CO　over　a　TiO2　supported　Au　nanoparticle　catalyst　(Au/TiO2).　It　is　found　that　the　visible-light　irradiation　can　promote　the　oxidation　of　CO　over　Au/TiO2.　Based　on　the　results　of　both　the　optical　absorption　of　Au/TiO2　and　the　adsorption　of　CO　over　Au/TiO2,　it　is　proposed　that　the　localized　surface　plasmon　resonance　(LSPR)　of　Au　nanoparticles　induced　by　the　visible-light　would　promote　the　adsorption　of　CO　and　its　activation　at　the　surface　of　Au　species,　resulting　in　the　promoted　oxidation　of　CO　over　Au/TiO2.　(C)　2012　Elsevier　B.V.　All　rights　reserved.
