In the present study, tin oxide thin film was prepared by a simple and inexpensive chemical evaporation technique from an aqueous solution at 673 K. Scanning electron microscopy, X-ray diffraction, Energy dispersive X-ray analysis and X-ray fluorescence were employed to characterize the resulting catalyst. The photocatalytic efficiency of the prepared catalyst was evaluated using para-chlorotoluene photodegradation in water, as an organic compound model. The reaction products are para-chlorobenzaldehyde and para-chlorobenzyl chloride. The formed products during the photoxidation of para-chlorotoluene are identified by coupled gas chromatography-mass spectrometry.
