Abstract：

The　catalytic　performance　of　Au/TiO2　for　oxidizing　CO　in　an　H2-rich　stream　under　visible　light　irradiation　was　compared　with　that　of　Au/Al2O3.　It　is　found　that　the　visible　light　can　promote　the　preferential　oxidation　of　CO　in　the　presence　of　H2　over　Au/TiO2,　while　it　promotes　the　oxidation　of　CO　but　suppresses　its　selectivity　in　the　same　case　over　Au/Al2O3.　The　chemisorption　results　show　that　this　visible　light　can　promote　the　adsorption　of　CO　in　the　presence　of　H2　and　its　activation　at　Au　sites　over　Au/TiO2,　but　suppress　the　adsorption　of　CO　over　Au/Al　2O3.　Based　on　the　photo-electrochemical　and　other　photo-response　performances　of　two　catalysts,　it　is　proposed　that　the　effect　of　visible　light　on　CO　adsorption　and　then　oxidation　over　the　supported　Au　catalyst　may　be　dependent　on　the　electron　transfer　behavior　between　Au　and　support　induced　by　the　localized　surface　plasmon　resonance　of　Au　nanoparticles.　©　2014　Elsevier　Inc.　All　rights　reserved.
