Selective　transformation　of　organics　by　visible-light-driven　photocatalysis　has　been　considered　as　a　green　and　efficient　strategy　for　the　synthesis　of　fine　chemicals.　Herein,　we　fabricated　mesoporous　structured　TiO2　with　CdS　nanoparticles　successfully　by　a　photodeposition　method.　The　photocatalytic　selective　oxidation　of　benzyl　alcohols　and　reduction　of　4-nitroaniline　were　demonstrated　over　the　as-prepared　samples　under　visible-light　irradiation.　The　CdS-decorated　TiO2　with　the　photodeposition　time　of　90　min　exhibited　highest　activity,　which　was　higher　than　that　of　the　commercial　CdS,　bare　TiO2,　CdS/P25,　and　CdS/SiO2.　Further　experimental　results　indicated　that　the　higher　performance　was　attributed　to　the　moderate　deposition　of　CdS　forming　a　closely　connected　heterojunction　with　TiO2,　which　promoted　the　separation　of　photogenerated　electrons　and　holes.　Based　on　the　results　of　active　species　detection,　possible　mechanisms　for　photocatalytic　selective　oxidation　of　benzyl　alcohol　and　reduction　of　4-nitroaniline　were　proposed.　Our　study　may　provide　guidance　for　selective　transformation　of　organics　via　construction　of　heterojunction　photocatalysts.
