Visible light stimulated binary nanostructure and defect enriched TiO₂-SnO₂ for photocatalysis and antibacterial activity

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.
