Design of plasmonic Ag-TiO₂/H₃PW₁₂O₄₀ composite film with enhanced sunlight photocatalytic activity towards o-chlorophenol degradation.

ABSTRACT: A series of plasmonic Ag-TiO₂/H₃PW₁₂O₄₀ composite films were fabricated and immobilized by validated preparation technique. The chemical composition and phase, optical, SPR effect and pore-structure properties together with the morphology of as-prepared composite film are well-characterized. The multi-synergies of as-prepared composite films were gained by combined action of electron-capture action via H₃PW₁₂O₄₀, visible-response induced by Ag, and Schottky-junction formed between TiO₂-Ag. Under simulated sunlight, the maximal K _app of o-chlorophenol (o-CP) reached 0.0075 min^-1 which was 3.95-fold larger than that of TiO₂ film, while it was restrained obviously under aci
