ABSTRACT: Mesoporous TiO2 ceramic films have been prepared upon the Ti alloy substrate by the micro-arc
oxidation (MAO) technology. To enhance the photo-catalytic property of the
films, Eu2O3 particles were added into the electrolyte
solution of Na2CO3/Na2SiO3.
Scanning electron microscope (SEM), energy dispersive (EDS), X-ray
photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) are employed to
characterize the modified films. Diffuse reflectance spectra (DRS) test,
photo-generated current test and photo decomposition test are applied to evaluate the
photo-catalytic property of the modified films. The results show that Eu2O3 transformed into one-dimensional (1-D) nano-wires embedded within the composite
film, and the film has high photo-catalytic property.
