A new facile in situ synthesis coating method was utilized to improve the photocatalytic activity of the textile fabric. An eco-friendly method of photoreduction was used to synthesize Ag/TiO2 nanoparticles. The synthesis and coating approaches were performed simultaneously. The elemental analysis of the X-ray photoelectron spectroscopy showed a pair of separated peaks with a binding energy of 6 eV between two states which confirmed the creation of silver metallic on the fabric surface. The field emission scanning electron microscope images and map analysis showed an even distribution of coating with nanoparticle size of 27 ± 5 nm. The self-cleaning properties were estimated by measuring the discoloration of reactive blue stain under UVA, UVC, and daylight irradiation and showed a significant increase in photocatalytic activity. The anti-bacterial property showed an excellent activity after Ag-doping in TiO2.
