Using tetrabutyl titanate as the precursor,silver nitrate as the load agent,silver-doped titanium dioxide coating film was prepared by sol-gel method.Three agent samples were characterized by X-ray diffraction( XRD) analysis to investigate the crystal structure,which confirmed a synergistic antibacterial effect.The antibacterial and preservative effects of silver-doped titanium dioxide coating film on Nanfeng citrus were investigated preliminarily. Nutritional indicators of ripe Nanfeng citrus before and after preservation were detected to investigate the preservative properties of silver-doped titanium dioxide coating film and compare the effects of different components of composite coating film. The results showed that Ag~+/TiO_2 composite coating film exhibited high antibacterial and preservative effects on Nanfeng citrus under visible light illumination condition.
Using tetrabutyl titanate as the precursor, silver nitrate as the load agent, silver-doped titanium dioxide coating film was prepared by sol-gel method. Novel agent samples were characterized by X-ray diffraction (XRD) analysis to investigate the crystal structure, which confirmed a synergistic antibacterial effect. The antibacterial and preservative effects of silver-doped titanium dioxide coating film on Nanfeng citrus were investigated preliminarily. Nutritional indicators of ripe Nanfeng citrus before and after preservation were detected to investigate the preservative properties of silver-doped titanium dioxide coating film and compare the effects of different components of composite coating film. The results showed that Ag ~ + / TiO_2 composite coating film exhibited high antibacterial and preservative effects on Nanfeng citrus under visible light illumination condition.
