A series of ultrafine K_2Ln_2Ti_3O_ 10 (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 indicate that highly ultrafine K_2Ln_2Ti_3O_ 10 can be accessible at lower fabricating temperature and shorter reation time by this approach. In addition, the investigation on their catalytical behavior based on the degradation of methyl orange under UV-Vis light suggests that the degradation rate can reach up to 60%.
