Abstract

This project aims at the synthesis, characterization and application heterojunction of nickel oxide (NiO) or copper oxide (CuO) with zinc oxide (ZnO) in photoelectrochemical degradation of trimethoprim and Levofloxacin antibiotics. The oxides will be produced by sol-gel method and hydrothermal and applied to glass surface by dip coating or paint for the formation of films of type NiO/ZnO and CuO/ZnO. The synthesis parameters and different methods of obtaining the oxides are studied to obtain films with a higher photocatalytic activity. The heterojunction NiO/ZnO and CuO/ZnO will be used as anode in photoeletrocatalytic degradation of emerging pollutants Trimethoprim and Levofloxacin. Physical characterization of the films will be made by techniques of X-ray diffraction, scanning electron microscopy and microanalysis by Energy Dispersive. The electrochemical characterization will be performed by voltammetric techniques and Electrochemical Impedance Spectroscopy. Photocurrent studies will be performed to the NiO, CuO and ZnO films individually and the results will be compared with the heterojunction NiO/ZnO and CuO/ZnO. The efficiency of the degradation processes of polluting species during fotoeletrocatalíticos experiments will be evaluated using the instrumental analytical techniques of spectrophotometry UV/Vis, high-performance liquid chromatography (HPLC) and total organic carbon analysis (TOC).
