Fabrication of Reusable Ceramic Film Based on Nanostructured Ag/Ag-TiO2 Materials for Photo Catalysis Applications | Chapter 7 | Challenges and Advances in Chemical Science Vol. 7

 The goal of this research is to develop low-cost, reusable nanostructured materials based on Ag/TiO2 for photocatalysis. Using a simple oxidation process of a Ti-Ag coating, vertical Agx/TiO2 nanorods were effectively produced. The samples were developed in a phase of ceramic-like materials that can be used for photocatalysis applications multiple times. By spin-coating silver nitrate onto Ti sheets, these ceramic-like Agx/TiO2 nanostructures were created. During the oxidation process, the presence of silver on the Ti sheet's surface aided the formation of one-dimensional nanostructures. By changing the concentration of silver on the Ti-sheet before oxidation, the physical properties of the produced ceramic-like nanostructures were examined. Nanostructures with an average size of 200–500 nm were developed as one-dimensional nanostructures. The nanostructure was vertically directed due to the presence of silver. In contrast to high silver concentrations, where the nanorods were very sparse at 40 mM, the nanorods were abundant at low and medium silver concentrations of 5, 10, and 20 mM. Pure TiO2 has an anatase and rutile structure with distinct diffraction lines A(101) and R(110); however, Agx/TiO2 has a dominating A(101) orientation, supporting 1D growth. The existence of TiO2 was confirmed by Raman spectra, which revealed the phonon modes associated with it. Methylene blue (MB) was used as a known target dye to test the photocatalytic capabilities of the produced ceramic-like nanostructures. In comparison to the pure and high-silver-concentration samples, the low- and medium-silver-concentration samples had high photocatalytic activity.
