Abstract :In this study, undoped and Zn-doped SnO 2 nanoparticles in different concentrations were synthesized by flame spray pyrolysis insert ignore into journalissuearticles values(FSP); technique. The produced particles were post-annealed after FSP process at 600 °C in order to obtain a crystalline structure. The structural analysis of the produced powders was performed by X-Ray Diffraction insert ignore into journalissuearticles values(XRD); methods. The surface morphology of the nanoparticles was identified using scanning electron microscopy insert ignore into journalissuearticles values(SEM);. In addition, photocatalytic degradation of aqueous methylene blue insert ignore into journalissuearticles values(MB); solutions were evaluated using undoped and Zn-doped SnO 2 nanoparticles under UV light illumination. Photocatalytic degradation of the MB solutions followed the pseudo-first-order-kinetics and the effect of the Zn doping amount on the photocatalytic reaction was investigated.
