Abstract
This work brings the two large band gap semiconductors TiO2 and SnO2 into composite catalyst for the visible light photodegradation of methyl orange (MO) dye. In this scenario, different ratios of TiO2-SnO2 nanocomposites were synthesized via sol-gel and precipitation methods. The variable compositions (TS 5% and TS 10%) are applied for the photocatalytic studies to destroy MO dye. Moreover, to the best of our knowledge for the first time, TiO2-SnO2 was focused against staphylococcus aureus bacterium.
