Abstract

Napretkom u području nanotehnologije porastao je interes za istraživanjem nanomaterijala. Nanomaterijali bazirani na titanijevom dioksidu (TiO2) su jedni od najčešće istraživanih u proteklih nekoliko godina te pronalaze primjenu u više područja, npr. solarne ćelije. jedna od najpragmatičnijih metoda priprave TiO2 nanocjevčica je metoda jetkanja elektrokemijskom anodizacijom. Cilj rada je izložiti folije titanije različitim plinovima pri različitim temperaturama u cijevnoj peći. Isto bi trebalo uvelike utjecati na pojavnost α ili β polimorfa titanija, koji se značajno morfološki razlikuju. Različita morfološka svojstva trebala bi biti odgovorna za različite uvjete rasta nanostruktura TiO2 te konačno na svojstva istih. Ovaj rad proučava parametre navedenog utjecaja. Za potrebe proučavanja mehanizama priprave uzoraka, isti će se karakterizirati odgovarajućim strukturnim i mikrostrukturnim tehnikama. Konačna primjena materijala je u solarnim ćelijama.

Abstract (english)

Interest in nanomaterial research has increased significantly with respect to progress in the field of nanotechnology. Nanomaterials based on titanium dioxide (TiO2) are among most researched in recent years and find broad applications, e.g. in solar cells. Among pragmatic methods for preparing TiO2 nanotubes etching by electrochemical anodization is found. The aim of the work is to process titania foils in different atmospheres at different temperatures in a tube furnace. This should greatly affect the occurrence of α or β polymorphs of titanium, each having distinct morphologic differences. Such morphological properties will be responsible for different growth conditions of TiO2 nanostructures and consequently their properties. In this work we want to observe the parameters of this influence. For the purpose, the samples will be characterized by appropriate structural and microstructural techniques. The end use of the material is for solar cells.
