ENHANCED PHOTOCATALYTIC DEGRADATION OF TETRACYCLINE BY TiO2 NANOTUBES COATED WITH TiO2 NANOFIBERS

The focus of this work is on the electrochemical synthesis of photocatalytic electrodes based on TiO2 nanostructures on Ti thin film and their efficiency in the degradation of tetracycline aqueous solution. In this study it was demonstrated that the surface characteristics of the developed photocatalyst have a very important influence on its optical and photocatalytic properties. This behavior was supported by correlation between the results from scanning electron microscopy and UV-Vis light technologies. Good performance was seen for the photocatalytic degradation of tetracycline in water using the manufactured TiO2 nanotubes coated with TiO2 nanofibers from suspension. This method may be applicable to the decomposition of other organic pollutants with the same chemical structures. © 2023, Politechnica University of Bucharest. All rights reserved.
