By　deposition　of　Au　nanoparticles　(Au　NPs)　onto　BiOCl　(BOC)　nanosheet　with　different　facets,　in　the　reaction　of　decomposing　Orange　II,　we　systematically　investigated　the　preferred　transfer　orientation　(PTO)　of　photo-generated　electron-hole　pairs　in　BOC　under　UV　light　irradiation.　Also,　the　active　oxidative　intermediates　during　the　degradation　process　were　also　studied.　Moreover,　the　Au　NPs　successfully　brought　about　visible　light　response　to　the　wide　gap　BOC,　while　the　exposed　different　facets　were　found　to　be　influential　on　the　surface　plasmon　resonance　(SPR)　effect.　The　present　work　may　contribute　to　a　deeper　sight　of　the　relationship　between　specific　facets　and　photo　catalytic　performance,　together　with　a　further　understanding　of　SPR-induced　photocatalytic　activity.　(C)　2014　Elsevier　B.V.　All　rights　reserved.
