Title

SOLAR LIGHT-INDUCED DECOLORIZATION OF SAFRANIN O USING UNMODIFIED AND GOLD-MODIFIED SEMICONDUCTOR OXIDES

Pages

  151-156

Abstract

 Unmodified and gold-modified semiconductor oxides were used for the complete DECOLORIZATION of non-buffered aqueous SAFRANIN O solutions. Photocatalytic properties of commercially available ZnO and TiO2 (anatase nanopowder) were compared with those of gold-modified ZnO (Au/ZnO). Au/ZnO was obtained from commercial ZnO powder through direct current sputter coating. ZnO-based catalysts show significantly higher DECOLORIZATION power in comparison with TiO2.Au/ZnO show slightly higher activity than unmodified ZnO. DECOLORIZATION of SAFRANIN O using Au/ZnO was additionally tested in different types of mineral water. The DECOLORIZATION efficiency in mineral waters was negatively correlated with the dry residue content (180oC) and in all cases was less than in distilled water. The inhibiting effect of hydrogen carbonate was additionally investigated.
