- Abstract
A comparative study regarding the shape, dimension and bactericidal activity of the undoped and Ag-doped TiO2 nanocrystals was achieved. In this way, two hydrothermal methods, classical hydrothermal and microwave-assisted hydrothermal, was used for nanoparticles synthesis. The obtained materials were investigated by X-ray diffraction, DRUV-VIS spectroscopy, BET and SEM/EDX analysis. Antibacterial activity of undoped and Ag-doped TiO2 materials was tested on real water from Bega River. The best bactericidal activity was proved by using Ag-TiO2 catalyst synthesized by microwave-assisted hydrothermal method, through damaging of E. coli colonies under visible irradiation.
