  • Characterization and photocatalytic activity of sepiolite-TiO2 and Na-montmorillonite-TiO2 catalysts 
    Sayınsöz, Elçin. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    This study focused on structural and photocatalytic properties of TiO2 incorporated Sepiolite and Na-Montmorillonite. Catalyst characterization was carried out by thermal gravimetric analysis (TGA), X-ray diffraction (XRD), ...
  • Montmorillonite and modified montmorillonite supported ZnO catalysts 
    Pekcan, Ayşe Hazal. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2015., 2015.)
    The purpose of this study is to prepare ZnO supported montmorillonite based catalysts by using co-precipitation technique. The photocatalytic activities of the as-prepared catalysts are studied for degradation/decolorization ...
  • Photocataltic propertirs of zeolite-based materials for gegradation of methyl orange 
    Yılmaz, Özge. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    Novel photocatalytic materials have been prepared by incorporation of TiO2 on ZSM-5 surface and incorporation of Y2O3, La2O3 and Ce2O3 on TiO2-ZSM-5 matrix. These materials have been characterized using scanning electron ...
  • Photocatalytic activities of ZnO-based materials: effect of rare-earth metal ion loading 
    Akalın, Şerife. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    In this study, pure and rare earth metal loaded ZnO photocatalytic materials have been prepared by coprecipitation method using the precursors of zinc and metal ions. These materials have been characterized by using scanning ...
  • Photocatalytic degradation of phthalic anhydride and dicarboxylic acids 
    Ökte, Ayşe Neren. (Thesis (M.S.)- Bogazici University. Institute for Graduate Studies in Science and Engineering, 1994., 1994.)
    Exposure of Ti02 particles to light with an energy equal or greater than its bandgap leads to the creation of electrons and holes which are able to degrade toxic chemicals. In this study, in the presence of Degussa P25 ...
  • TiO2 and ZnO loaded fly ash catalysts 
    Tuncel, Duygu. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    In this study, two binary catalysts TiO2 supported fly ash (TiO2-FA) and ZnO supported fly ash (ZnO-FA) were sythesized by sol-gel and co-precipitation technique. The as-prepared catalysts were characterized by using several ...
