20.500.12556/RUL-119797 Nanos TiO2-fotokatalizatorja na milimetrske granule Application of photocatalyst TiO2 to millimetre-sized granules 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. 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. polprevodniška fotokataliza titanov dioksid čiščenje vode semiconductor photocatalysis titanium dioxide water purification true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2020-09-11 09:55:00 2020-09-11 09:55:04 2022-08-31 03:54:46 0000-00-00 00:00:00 2020 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 12981 32517123 Sitnikova_Natalija_-_Nanos_TiO2-fotokatalizatorja_na_milimetrske_granule.pdf Sitnikova_Natalija_-_Nanos_TiO2-fotokatalizatorja_na_milimetrske_granule.pdf 1 A2F231892105E1ED22015A327D6FAB26 a3c65522afcefd15436296fc7a2f73e3283121b53fffe186204afa74c6a711d5 ec8e8991-a1b9-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=134532 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
