Sillenite type Bi2 5 FeO 40 has been used as the research subjects in this paper.Various Morphologies of Bi2 5 FeO 40 nano-materials have been successfully synthesized by hydrothermal method on the titanium substrate. The effect of processing parameters such as reaction temperature(1 60-200 ℃),mineralizer and stoichiometry was investigated by XRD and FE-SEM.Bi2 5 FeO 40 are found to have a good visible response ability from 400 to 600 nm through UV-Vis diffuse reflectance spectroscopy.The photo-electrochemical properties were measured by three electrodes measurements.The sample of nanorods morphology responded rapidly when irradiation.
