The Ni-P-TiO2 coatings were successfully obtained on foamed nickel by electroless plating technique. Materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive analysis (EDS) studies. The degradation effect of the prepared coating for the dyes was studied at the same time. Results showed that the appearances of coatings were fine and the amount of TiO2 in the coatings reached at 9.85wt%. The specimens exhibited excellent photocatalytic activity, the decolorization ratio of reactive black GR and methylene blue reached to 92.40% and 95.27% after 4 hours and 6 hours respectively irradiated by the same ultraviolet lamp.
