Abstract:
This thesis is devoted to the synthesis and characterization of nanostructured
films, and then used them in photocatalytic applications.
The first part focused on the synthesis of material: SnO2, and Sr‐doped SnO2
nanostructured films. One method was used for the preparation of the films,
with varied and controlled properties: Sol‐gel method and deposited on the glass
by dip‐coating technique.
In the second part, various physical and chemical characterizations such as:
XRD,Raman, UV‐visible and AFM were presented.
Finally, we tested the photocatalytic efficient of tin dioxide and (8%) Sr‐doped
SnO2 under UV and Solar irradiation regarding Methylene Blue dye degradation,
the photocatalytic activity of (8%) Sr –doped SnO2 films were much higher than
that of the undoped SnO2.
