Forster　resonant　energy　transfer　(FRET)　is　critical　hindrance　for　improving　the　solar-energy-conversion　efficiency　via　the　near-field　electromagnetic　energy　transfer　(NEET)　mechanism　in　the　plasmonic　nanostructure-involved　photocatalysts.　Herein,　a　plasmonic　nanoparticle/graphene/semiconductor　ternary　model　system　is　fabricated　successfully.　In　this　fabrication,　the　thin　graphene　(RGO)　layer　covers　completely　the　semiconductor　with　different　facets　exposed,　and　the　plasmonic　nanoparticles　are　separated　from　the　semiconductor　in　a　proper　distance.　This　unique　architecture　raises　a　new　opportunity　to　optimize　surface　plasmon　resonance　(SPR)　effect　in　plasmonic　nanostructure-involved　photocatalysts　by　the　dual　modulation　of　interfacial　layer＇s　thickness　and　fluorescent　frequency,　resulting　a　tremendous　improvement　in　the　rates　of　photocatalytic　reactions.　Furthermore,　this　predictive　model　provides　a　new　idea　for　the　design　of　high-efficient　photocatalysts　and　may　upper　limits　of　SPR-mediated　enhancement　of　photocatalytic　performance　for　plasmonic　nanostructure-involved　photocatalysts.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
