Abstract：

A　simple　hydrothermal　reaction　is　used　to　synthesize　a　truncated　tetragonal　bipyramid　BiVO4　with　exposing　{010}　and　{110}　facets.　Pt　is　deposited　on　BiVO4　surface　respectively　under　visible　light　or　ultraviolet　light　irradiation.　Pt　deposition　is　quite　different　in　particle　size,　uniformity,　and　tightness　of　contact　with　catalyst,　because　of　the　different　growth　rate　of　Pt　with　different　light　sources.　The　visible-light-deposited　Vis-Pt/BiVO4　is　superior　to　UV-Pt/BiVO4　in　photocatalytic　activity　toward　the　selective　photoxidation　benzyl　alcohol　into　benzaldehyde.　This　work　demonstrates　that　the　status　of　Pt　photodeposition　is　influenced　by　the　photon　energy　and　thus　the　photocatalytic　efficiency.
