Preparation and characterization of titanium dioxide photocatalyst

Abstract

The bachelor thesis is focused on the preparation and characterization of photocatalytically active titanium dioxide. Nanostructured titanium dioxide is outstanding photocatalyst finding a variety of applications from the water treatment to its utilization in energetic. This bachelor thesis focuses on the preparation of the titanium dioxide using the sol-gel method. Titanium tetraisopropoxide was used as a titanium precursor. The samples were prepared in the form of powder as well as in the form of thin layers deposited on the glass substrate. The prepared samples were characterized using methods of chemical and phase analysis, the morphology of the samples was studied using microscopy techniques. The prepared samples were examined for evaluation of their photodegradation activity.
