A series of plasmonic Ag-TiO2/H3PW12O40 composite films were fabricated and immobilized by validated preparation technique. The chemical composition phase, optical, SPR effect pore-structure properties together with the morphology as-prepared film are well-characterized. multi-synergies gained combined action electron-capture via H3PW12O40, visible-response induced Ag, Schottky-junction formed between TiO2-Ag. Under simulated sunlight, maximal K app o-chlorophenol (o-CP) reached 0.0075 min-1...
Kinetics is crucial for photoelectrocatalytic degradation of organic contaminants. A 12-tungstophosphoric acid/titania (H3PW12O40/TiO2) composite film was prepared by the sol-gel-hydrothermal route to investigate optimal conditions and kinetics o-chlorophenol (o-CP).
