The nanosize Cu-doped TiO2 was synthesized by mechanical alloying (MA). The synthesized powders were characterized by XRD and TEM for structural analysis, UV-DRS and PL for the optical study and TOC for photocatalytic behavior. The Cu-doped powder had a rutile phase in which the added Cu atoms were uniformly dissolved. Optical studies showed that the absorption wavelength of Cu-doped powders moved to visible light range (red shift) which was believed to be induced by the Cu trapping energy level. The carbon decomposition rate of Cu-doped powders was faster than other powders (P-25, HPPLT). |
