In this work, nanostructured titanium dioxide (TiO2) thin films have been prepared on glass substrates using a facile layer-by-layer dip-coating method. The nano-layer surface was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis. It was observed that degradation of Acid Red 14 (AR14) depend on several parameters such as pH, the coting of silver and dipping times. In addition, TiO2 from TiO2 /Ag demonstrated photocatalysis performance when irradiated and the Ag carrier further showed an electron-scavenging ability to mitigate electron-hole pair recombination, which can improve the photocatalytic efficacy. With the oxidization and electron-scavenging ability of Ag and the photocatalysis ability of TiO2 and TiO2/Ag can decolor AR14 more efficiently than TiO2.
