摘　　要：A series of uhrafine K2Ln2Ti3O10（Ln = La, Ce, Pr, Nd, Sm, Eu, Dy）photocatalyst was prepared by microemulsion method based on tetrabutyl titanate reacting with potassium hydroxide and lanthanumoxide. The obtained products were characterized by XRD, TEM and UV-Vis spectra. These results indieate that highly ultrafine K2Ln2Ti3O10 can be accessible at lower fabricating temperature and shorter reation time by this approach. In addition, the investigation on their eatalytieal behavior based on the degradation of methyl orange under UV-Vis light suggests that the degradation rate can reach up to 60%.A series of uhrafine K2Ln2Ti3O10（Ln = La, Ce, Pr, Nd, Sm, Eu, Dy）photocatalyst was prepared by microemulsion method based on tetrabutyl titanate reacting with potassium hydroxide and lanthanumoxide.
