Ag/SnO2 films were fabricated over silicon (Si) (111) substrates by sol gel technique, and dipping method and evaluated for photocatalytic application to decompose methylene blue (MB). Structural, morphological, and optical measurements were investigated using XRD, AFM, SEM, and UV-Vis DRS spectroscopy. SEM images showed that the Ag/SnO2 thin films were homogeneous and the particle size increased with increasing Ag doping content. The optical properties illustrated as Ag doping content increased, energy gap values of Ag/SnO2 films reduced. Results showed the best Ag doping was 6wt%, with 82% degradation efficiency and obvious constant (𝑘app) of 9.68 × 10−3 min−1 after 3 h under UV irradiation.
