Sobre IBD

W niniejszej pracy opracowano syntetyczną drogę przygotowania nanokompozytów SiO₂/TiO₂ w procesie zol-żel, ze stosunkami krzemu i tytanu 80:20, 70:30 i 55:45. Nanokompozyty scharakteryzowano za pomocą analizy chemicznej, SEM, EDS, FTIR, dyfrakcji rentgenowskiej, pomiarów powierzchni właściwej i techniki odbicia rozproszonego. Wykorzystując technikę odbicia rozproszonego możliwe było określenie energii przerwy energetycznej pasma, a przy użyciu modeli matematycznych możliwe było skorelowanie zmierzonej energii przerwy i przybliżone określenie wielkości nanokrystalitów. Badanie fotodegradacji błękitu metylenowego w roztworze wodnym przy użyciu przygotowanych materiałów i naturalnego światła słonecznego przeprowadzono przy różnych czasach kontaktu, pH i stężeniu roztworu, w celu zaobserwowania zmian wydajności fotodegradacji w zależności od zmian proporcji krzemu i tytanu w matrycy.
