Problem statement: Since bacteria mainly causes damage on fresh vegetables and fruits during transportation to market, anti-bacterial TiO2 photocatalyst was applied for their packaging films. However, it has been known that pure TiO2 exhibits low photocatalytic property due to rapid recombination of photo-activated electrons and holes. Doping with metal or metal oxide shows the improvement of photocatalytic activity and disinfection effect. Approach: Fe3+ was considered to dope into TiO2/3SnO2 photocatalyst in order to enhance the photocatalytic property and bacterial inactivation efficiency. The Fe3+ doped TiO2/3SnO2 nanoparticles were prepared by sol-gel method and calcined at 400
