Abstract

Paper–TiO2–Ag2O floating photocatalysts were produced under mild condition and their photocatalytic activityfor the degradation of aromatic amine under sunlight stimulant was investigated.Characterizations by Raman, XRD, XPS, DRS and PL confirmed the presence of TiO2 and Ag2O, and themorphology of the appended TiO2/Ag2O layer was probed by FE-SEM. The photocatalytic activity of the prepared samples was investigated by the degradation of aniline (AN) in water under simulated sun-light illumination and constrained conditions, i.e. non-stirring and non-oxygenation. The presence of Ag2O combined with TiO2 was shown to improve the resistance of paper to bacteria attack, thus increasing the durability of thephotocatalyst. Thanks to its hydrophobic character, the paper–TiO2–Ag2O NPs can be employed as useful floating photocatalyst and can be reused in continuous cycles.
