%X TiO2 composite nanoparticles were synthesized by adding iron salt and surfactant Cetyl trimethyl ammonium bromide (CTAB) into the sol-gel process of Tetrabutyl titanate (TBOT). The composite particles, whose absorption maximum was appeared in about 530nm, showed the photocatalytical activity toward Rhodamine B. The effect of Fe3+ mass on the structure and properties of composite materials was systematically studied. Some means such as TEM, XRD, TG-DTA and UV-Vis were used to character these particles. The results showed, that the Fe3+ iron was doped in the crystal lattice of TiO2 and the new bandwidth (Eg=1.37eV) was appeared. Because of that, the spectral response property of TiO2 composite materials was changed into visible light range.
