[Spectral research on the effect various metal ions on the of photocatalytic degradation properties of TiO2 nanocrystal].

TiO2 nanocrystalline was prepared by a emulsion method in the mixed solvent of cyclohexane and acetic anhydride using, titanyl organic compound as the precursor. The prepared product was characterized by means of X-ray diffraction (XRD) and Fourier transform infrared spectrum (FTIR). The photocatalytic oxidation of methyl orange with TiO2 loaded with various metal ions was discussed.
