Effect of Silver Modification on the Photoactivity of Titania Coatings with Different Pore Structures.

ABSTRACT: Nanostructured photoactive systems are promising for applications such as air and water purification, including self-cleaning coatings. In this study, mesoporous TiO₂ sol-gel coatings with different pore structures were prepared and modified with silver by two methods: the "mixing" method by adding AgNO₃ to the precursor sol, and the "impregnation" method by immersing the samples in AgNO₃ solution (0.03 and 1 M) followed by heat treatment. Our aim was to investigate the effects that silver modification has on the functional properties (e.g., those that are important for self-cleaning coatings). Transmittance, band gap energy, refractive index, porosity and thickness values were determined from UV-Vis spectroscopy measurements. Silver content and structure o
