Synthesis of Mn and Se-Doping TiO₂ Mesoporous Materials and their Antibacterial Efficacy under Visible Light Irradiation

Abstract:

Two kinds of visible light driven mesoporous structured Mn and Se-doping TiO₂ nanocrystal photocatalysts have been synthesized through a modified sol-gel method, and N₂ adsorption-desorption isotherm confirms that the mesoporous materials possess large pore size and narrow pore size distribution. X-Ray powder Diffraction (XRD) analyses reveal that the doping of Mn and Se inhibits the growth of TiO₂ anatase nanocrystal and the Mn species are higher dispersed on the surface of TiO₂. Ultraviolet (UV)-vis spectrum demonstrates the excellent adsorption property of Mn doping TiO₂ for visible light region, which enables this novel photocatalysis material to possess remarkable activity in photocatalytic antibacterial for E. Coli. bacteria under visible lights radiation.
