Sb doped nano titanium dioxide powders were prepared by hydrothermal method. Samples were then characterized using SEM or XRD. The results indicated that all samples were anatase phase TiO 2 and the particle sizes were all under 10nm. The DRS experiments showed that light absorption was improved when the Sb 3+ was doped properly. Moreover, we discussed about the red shift of DRS and brought forward lumi nescence mechanistic of TiO 2 with Sb doping according to the fluorescence emission spectra. At last, the photocatalytic degradation of methyl orange was tested for all samples, and the photocatalytic efficiency was greatly enhanced when the 0.5% Sb 3+ was d oped..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
