Fabrication of TiO2 Monolithic Photocatalyst and Evaluation of its Antibacterial Activity under Simulated Solar Irradiation

In this study, the TiO2 nanoparticles were coated on the monolithic surface by a dip-coating technique. Characterization of synthesized samples was determined by X-ray diffraction. Antibacterial application of the samples was investigated under simulated solar irradiation on Escherichia coli (E. col...
