In this study, to enhance the photocatalytic activity of TiO 2 nanorods in the degradation of complex organic pollutants such as textile dyes, the fabrication of the silver-doped TiO 2 nanorods in the sol-gel method has been accomplished. To provide optimal conditions for the optical degradation of methylene blue dye, nanostructural and photocatalytic properties of TiO 2 nanorods have also been investigated. The crystalline phases, lattice strain, and specific surface area of nanoparticles were investigated by the XRD. The morphology of the nanoparticles was analyzed using AFM plus SEM. The FTIR determined the existing chemical bonds. The effect of calcination on the optical properties and the rate of photodegradation of nanorods was studied. The optical bandgap of the nanorods was estimated by the DRS method and verified by the Tauc method. The obtained results showed that nanorods without calcination revealed the smallest crystal size, the highest effective area, the lowest optical band gap, the highest optical degradation rate, and the highest dye removal efficiency. The results indicated that the nanorods were reliable candidates for the degradation of organic pollutants, especially textile dyes.
