| Popis: |
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. |
