| Abstract: | The neodymium ion doped-TiO2 nanoparticles were prepared by sol-gel method,and the effects of neodymium ion doping on phase transformation and photocatalytic activity of TiO2 were investigated.The results of XRD analysis showed that neodymium ion doping-TiO2 was dominated by anatase and inhibited the increase of the crystallite size.The results demonstrated that the degradation of methyl orange under UV radiation was more efficient with Nd3 -TiO2 catalyst than with pure TiO2,and an optimal dosage of neodymium ion at 1.5% achieved the highest degradation rate for methyl orange. |
