Abstract: Tin oxide (SnO2) nanoparticles (NP) has been intensely investigated as photo catalyst for water purification and environment decontamination, while the photon generated electron and hole pair (EHP) recombination is one of factors limiting its efficiency. Tin oxide/Graphene oxide (SnO2/GO) nanocomposite is very promising to overcome this limitation for photo catalytic applications. GO, with its unique electronic properties, large specific surface area and high transparency, contributes to facile charge separation and adsorptivity in this hybrid structure. The SnO2/GO composite under sunlight photo catalytic degradation of methylene blue (MB) has been investigated in aqueous heterogeneous suspensions. It may be used either alone or in combination with H2O2 to enhance their performance and control of bio growth (slime). The hydrogen peroxide may also be used to speed up catalysts reactions for complete degradation. The SnO2/GO composite showed an enhanced photo catalytic degradation activity for the organic dye methylene blue under sunlight compared to bare H2O2. Degradation of methylene blue under sunlight is fast with in 10min with the combination of SnO2/GO and H2O2 as a photo catalyst. The study of the prepared SnO2/GO composite under the sunlight photo catalytic activity of photo catalyst was investigated by the colorimeter by observing the optical density with reference of distilled water.
