Abstract: |
The Ni-P-TiO2 composite films on stainless steel was prepared by electroless composite plating method. The composite films were characterized by means of energy dispersive spectrometry (EDS) , X-ray diffraction (XRD) ,UV visible absorption spectra(UV-Vis) and infrared spectra（IR）. The photocatalytic activities of the Ni-P-TiO2 composite films were evaluated by decolorization of methyl orange under visible light irradiation. The results showed that the P and Ni on the Ni-P-TiO2 composite films led to the lattice distortion, and formed a new energy gap, which could extend the absorption edge to the visible light region. Under the condition of 4h visible light irradiation, the degradation ratio of methyl orange exceeds 67%. The visible photocatalytic activity of TiO2 is highly improved.
