The use of titanium dioxide in the degradation water pollutants encounters several challenges, including particle agglomeration leading to a reduction its specific surface area and high rate photogenerated electron-hole recombination, resulting lower quantum efficiency. Therefore, this work, we first employed sepiolite load dioxide, mitigating agglomeration. Building upon this, tin was coupled with it enhance charge separation. SnO2/TiO2/sepiolite photocatalytic composites were synthesized using sol–gel method at 450 ℃. underwent thorough characterization encompassing phase composition, morphology, chemical valence states, area, optical properties, activity. outcomes demonstrate an augmentation TiO2/Sep following (Sep) loading. Among these, composite (with Sep: TiO2 mass ratio 10 %) exhibited most favorable performance, displaying first-order reaction constant 0.010 min−1, surpassing that pure by factor 2.0. introduction SnO2 expedited migration across interfaces, curbing recombination pairs, thus enhancing In light presence sepiolite, addition further amplified performance. Optimal results achieved when molar SnO2:TiO2 set 1:4, highest efficiency observed SnO2/TiO2/Sep composite.
