In this work, SnO2 nanoparticles with the variation of annealing temperature (400°C-800°C) were used as photocatalyst for remove organic dye from the aqueous solution. SnO2 nanoparticles were synthesized using sol-gel method. For enhancing the stability and the photocatalytic activity of the samples, magnetite materials (Fe3O4) were combined with SnO2 nanoparticles. The prepared samples characterized by X-ray Diffraction (XRD). The X-ray diffraction shows tetragonal structure of SnO2 and cubic spinel of Fe3O4 as the components of the prepared nanocomposites. The photocatalytic activity of the samples was studied using Methylene Blue (MB) as a model organic pollutant. The photocatalytic degradation of MB by SnO2 and Fe3O4 nanocomposites under UV light irradiation was examined by varying the operational parameters such as catalyst dosage and scavengers. Among the variation annealing temperature of SnO2 nanoparticles, the 700°C annealing temperature of SnO2 showed the highest photocatalytic activity. The repeatability of photocatalytic activity was also tested.
