Environmental pollution on a global scale has drawn attention to the need for totally new environmentally friendly and clean processes, which are challenges facing researchers working in the field of green chemistry. In fact, natural water environment today is threatened by different concentrations of hazardous chemical substances. It is therefore, of utmost urgency to develop ecologically friendly, clean and safe technologies, materials and processes to sustain the present level of population and economic expansion. The treatment technologies include synthesis and developing new materials by simple techniques, low expenses within a short time. The current treatment trend of the contaminated water has moved from phase transfer approaches towards complete destruction of pollutants using for example, advanced oxidation processes (AOPs). Photocatalysis is finding renewed interest for (AOPs) as environmentally friendly green chemistry approach. This technique involves reactive free radical species for non-selective destruction of pollutants to harmless and eco-friendly end products, which are substantiated by the various characterization techniques. Tin oxide (SnO2) has a high band gap is doped with different materials such as rare earth, transition metals and halogens (iodine). Doped tin oxide will be visible light active which also could be used in solar energy for activating the Photocatalysis process.
