[14p-PA13-18] Crystal and Electronic Structure of Mo and N co-doped Anatase TiO2
Keywords:photocatalyst,TiO2,co-doped
Titanium dioxide (TiO2) has been attracting attention as a highly efficient photocatalyst. However, it can be excited only by ultraviolet light, because of the wide band gap (3.0 – 3.2 eV). For more efficient use of solar energy in photocatalytic reaction, therefore, it is necessary to extend the optical response of TiO2 to the visible light region. One of the method synthesizing visible light active photocatalyst is co-doping of nonmetal and metal elements. High activity under visible light is expected because of the compensation effect. Compensation effect is the transfer of electron between non – metallic ions and metal ions.
In previous studies, co-doping TiO2 samples were mainly fabricated by liquid phase growth method. However, it was difficult to control the concentration of dopants accurately by liquid phase growth method. In this research, molybdenum and nitrogen doped anatase TiO2 were fabricated by pulsed laser deposition( PLD ) that enables to control the dopant concentration.
