Abstract：

Novel　visible-light-driven　plasmonic　Au/CdMoO4　photocatalysts　were　synthesized　by　hydrothermal　process　following　chemical　reduction　process.　The　catalysts　were　characterized　by　X-ray　diffraction,　transmission　electron　microscopy,　UV-vis　diffuse　reflectance　spectroscopy　and　X-ray　photoelectron　spectroscopy.　The　results　show　the　catalysts　exhibited　strong　visible　light　absorption　due　to　the　surface　plasmon　resonance　effect　of　Au　nanoparticles.　Compared　to　CdMoO4,　Au/CdMoO4　composites　displayed　superior　photocatalytic　activities　for　the　selective　oxidation　of　benzylic　alcohol　to　benzaldehyde　under　visible　light.　The　highest　conversion　was　obtain　by　the　1.6%　Au　loaded　CdMoO4.　The　mechanism　for　the　selective　oxidation　of　benzylic　alcohol　in　the　Au/CdMoO4　system　is　proposed.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
