Description :
Visible light active nano silver zirconate has been prepared by Co-precipitation method and the effect of silver modification was studied. Nano Ag2ZrO3 has been prepared by mixing high-purity 0.1 M AgNO3 and 0.1 M ZrOCl2 .6H2O solutions in 2:1 ratios. The structural and optical properties were characterized by X-ray diffraction and UV- VIS diffuse reflectance spectroscopy. The band gap of the sample was determined by the equation Eg = 1239.8/λ. The band gap of nano Ag2ZrO3 was found to be 2.6 eV which is lower than Ag2ZrO3 (2.9 eV) synthesized by solid state reaction method. These values show that both the samples are visible light active and have low band gap than TiO2 and ZrO2.
Keywords: Nano silver zirconate, Co-precipitation method and band gap.
