Abstract

Potassium and strontium niobate (KSr2Nb5O15) of tungsten structure (TB) bronze was doped with nickel (Ni2+) with stoichiometry type KSr2NixNb5-xO15-#x3B4; onde x = 0,25; 0,50 and 0,75. The powders were prepared by chemical synthesis using the modified Polyol method, and characterized by infrared spectroscopy with Fourier transform (FT-IR), by X-ray diffraction (XRD), including the network parameters (relative intensity - IR(KSNNi0,50) #x2C3; IR(KSNNI0,25) #x2C3; IR(KSNNI0,75) ) and crystallite size. The effects of doping (Ni2+) in the process of photo degradation were studied, the absorbance as a function of time for the Basic Blue dye 41 result from the photo degradation performed with the photo catalyst KSNNi0,50 presented a lower absorbance value, and the spectrophotometer was used in the UV-vis region.
