Abstract
Cilj ovog rada bio je elektrokemijski okarakterizirati metalne okside koji se koriste u procesu fotokatalize. Provedeno je ispitivanje nanokompozita TiO2/SnS2 u otopini NaCl, s dodatkom i bez dodatka diklofenaka (DCF) te u otopini Na2SO4, s dodatkom i bez dodatka DCF. Osim toga, provedeno je ispitivanje elektrokemijski formiranog TiO2, koji je dobiven metodom kronoamperometrije na način da je titanska elektroda polarizirana tijekom 120 s na potencijalu od 1 V. Nanokompozitni fotokatalizator TiO2/SnS2 pripremljen je hidrotermalnom sintezom, a imobilizacija na titansku elektrodu je provedena metodom rotacijskog nanošenja. Elektrokemijske metode karakterizacije koje su korištene u ovom radu su ciklička voltametrija (CV), elektrokemijska impedancijska spektroskopija (EIS) i Mott-Schottky analiza. Pokazano je da je zaista došlo je do adsorpcije DCF-a na površinu fotokatalizatora, budući da se impedancijski spektar promijenio nakon njegova dodatka. Također, u ovom radu je dokazano da adsorpcija organskih tvari utječe na svojstva vanjskog, poroznog i unutarnjeg, kompaktnog sloja fotokatalizatora te na formiranje sloja prostornog naboja.
Abstract (english)
The objective of this research was electrochemical characterization of the metal oxide used in the photocatalytic processes. A study of the nanocomposite TiO2/SnS2 was performed in NaCl solution, with and without addition of diclofenac (DCF) and in Na2SO4 solution, also with and without DCF. In addition, an electrochemically-formed TiO2 was also tested. The electrochemically-formed TiO2 was obtained by using chronoamperometry method by polarization of titanium electrode for 120 s at potential of 1 V. The nanocomposite photocatalyst TiO2/SnS2 was prepared by hydrothermal method and immobilization on titanium electrode was carried out by spin-coating method. Methods of electrochemical characterization used in this work were cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and Mott-Schottky analysis. In the presence of DCF in the investigated solution the impedance spectrum was changed due to the DCF adsorption on the photocatalyst surface. It was also shown that adsorption of organic substances influence the properties of the outer, porous layer and inner, compact layer of the photocatalysts, as well as space charge layer.
