摘要: The plasmonic Ag-TiO2 (with 0.5 wt% Ag) photocatalyst was prepared on P25 TiO2 surface. presence of AgNPs the titania indicated by UV–vis spectrum, which showed a absorbance band in visible range (λmax = 455 nm). XPS measurements suggested that Ag metallic (Ag) and oxide forms TiO2. were embedded [poly(ethyl acrylate-co-methyl methacrylate; p(EA-co-MMA)] copolymer to attain mechanically stable, photocatalytically active nanocomposite films. photooxidation ethanol slower photocatalyst/polymer nanocomposites, but it could be significantly improved irradiating them with UV light. photoaging applied as post-preparation treatment improve photocatalytic activity Changed surface morphology partial destruction polymer supported AFM FTIR results. Contact angle used determine free energies photoaged
