Chrome doped nanoTiO2transparent hydrosol was synthesized by a complexation-controlled hydrolysis method at room temperature. The absorbance spectrum and phase structure of samples were characterized by UV-Vis spectrophotometer, and X-ray diffraction, respectively. The photocatalytic activity by degradating acid red 3R dye was studied, and the results indicated that when nanoparticle doped with 0.5% Cr, the degradation rate exceeded 96% for 60 min under the sunlight.
