Abstract

Svetovno pomanjkanje vode predstavlja velik izziv sodobni družbi. Potencialen vir vode predstavlja ponovna uporaba odpadne vode, vendar jo moramo pred uporabo prečistiti. Ker so nekatera onesnažila zelo trdovratna, jih je nemogoče odstraniti s konvencionalnimi metodami, zato se je treba obrniti k naprednim oksidacijskim metodam. V tej diplomski nalogi sem raziskala eno izmed njih – polprevodniško fotokatalizo. Sintetizirala sem tri vrste raztopin z nanodelci TiO2 za nanos na milimetrske granule ter testirala njihovo fotokatalitsko aktivnost. Preizkusila sem proces žganja granul z nanosi. Testirala sem vpliv prepihovanja vzorca s kisikom na aktivnost fotokatalizatorja.

Secondary title: Application of photocatalyst TiO2 to millimetre-sized granules
Secondary abstract: The global water shortage is a challenge for modern society. Wastewater could be used as a potential source of water, but it must be properly treated before it can be used. Due to the persistence of some pollutants, advanced oxidation processes may be used in parallel with conventional water treatment processes. The aim of this work was to test one of the advanced oxidation processes - semiconductor photocatalysis. I synthesised three types of solutions with titania nanoparticles to coat millimetre-sized granules and test their photocatalytic activity. I also tested the process of thermal treatment of the granules with the coating. The influence of oxygen purging during the photocatalytic measurements was also tested.
