In a series researches so far, it has been shown that TiO2 nanoparticles have become the focus of intensive exploration in the field of photocatalysis, as a consequence of their unique properties and potential applications. In order to improve photocatalytic and functional properties of TiO2 nanoparticles, different methods should be used. One of the most effective approaches is capping of nobel metal (Pt, Ag, Au) clusters on nanoparticle surface. Namely, metal clusters act as electron traps and they promote interfacial charge- -transfer processes and reduce undesirable recombination processes on TiO2 nanoparticle surface. As a consequence, photocatalytic efficiency of the system should be improved. The cotton fabric modified by TiO2/Ag nanoparticles was synthesized by in situ photoreduction of Ag+-ions on alanine modified TiO2 colloidal nanoparticles previously deposited onto cotton fabric. Adsorption of Ag+-ions on TiO2 nanoparticle surface was improved by addition of alanine amino...-acid. As a result, separation of photoinduced charges is preferred and recombination process is significantly reduced. In order to further improve the efficiency of the system, methyl alcohol was employed as hole-scavenger. Obtained results confirmed the presence of TiO2/Ag nanoparticles across the surface of cotton fabric (SEM), as well as successful fabrication of metallic Ag on investigated fabric (XRD). Interaction between alanine modified TiO2 and Ag nanoparticles was studied by FTIR, while structural properties of synthesized samples were investigated by Raman spectroscopy. The photocatalytic performance of TiO2/Ag nanoparticles modified cotton fabric was tested in the process of photodegradation of organic dyes under simulated solar light: Rhodamine B, Acid Orange 7 and Methyl Red.
