TiO2 photocatalysis has attracted much attention recently for environmental protection,because of its inexpensive,non-toxic and photoelectric properties that can be exploited for several technical applications.However,the photocatalytic efficiency of pure TiO2 is so limited that researchers are seeking a new way or material to solve rapid recombination of photogenerated electron-hole pairs and limited wavelength scope of photocatalytic.
