Abstract
Cilj ovog rada bio je prirediti i karakterizirati elektrode WO3 i WO3 - BiVO4 te ih ispitati u fotoelektrokemijskom proces razgradnje 0,1 mmol/dm^3 amoksicilina. Elektrode su se okarakterizirale metodama linearne polarizacije, kronoamperometrije, OCP, elektrokemijske impedancije i Mott - Schottky. Sve metode su provedene u uvjetima osvijetljenosti i neosvijetljenosti, a kao izvor svijetla služila je LED lampa. Fotoelektrokemijski proces razgradnje amoksicilina pratio se metodom kronoamperometrije. Tijekom ovog procesa uzimali su se uzorci u razmacima od pola sata kako bi se promjena koncentracije pratila UV/Vis spektrofotometrom. Iz rezultata se uočava kako dolazi do pojave fotostruja što ukazuje da dolazi do uspješnog stvaranja parova elektron - šupljina. Mjerenja su pokazala kako najbolja fotoelektrokemijska svojstva pokazuje elektroda s elektrodepozicijski nanesenim BiVO4 na sloj WO3. Tijekom fotoelektrokemijskog procesa dolazi do razgradnje amoksicilina što znači da su elektrode uspješno pripravljene.
Abstract (english)
The aim of this work was to prepare and characterize WO3 and WO3 - BiVO4 electrodes and to test it in the photoelectrochemical process for degradation of 0.1 mmol/dm^3 amoxicillin. Methods used in this work were linear polarization, chronoamperometry, OCP, electrochemical impedance and Mott - Schottky. All methods were performed under light and dark conditions where the light source was a LED lamp. The photoelectrochemical process of amoxicillin degeadation was monitored using the chronoamperometry method. During this process, samples were taken at intervals of half an hour in order to monitor the change in amoxicillin concentration with an UV/Vis spectrophotometer. From the obtained results, it is evident that a photocurrent appears, which indicates that there is a successful formation of electron - hole pairs. The investigations showed that the best photoelectrochemical properties are obtained for the electrode with BiVO4 electrodeposited on the surface of WO3 layer. During the photoelectrochemical process, the decomposition of amoxicillin was detected, which means that the electrodes have been successfully prepared.
