Goethite–titania composite: disinfection mechanism under UV and visible light por Lara Rico, Rosalina, Múzquiz Ramos, Elia M., López Badillo, Claudia M., García Pérez, Ulises Matías, Cruz Ortiz, Brenda R.

“…The structural, morphological and optical properties of as-synthesized composites were characterized by X-ray powder diffraction, scanning electron microscopy and UV-Vis diffuse reflectance spectroscopy, respectively. a-FeOOH–TiO2 composites and TiO2-P25, as reference, were evaluated as photocatalysts for the disinfection of Escherichia coli under UV or visible light in a stirred tank reactor. a-FeOOH–TiO2 exhibited better photocatalytic activity in the visible region than TiO2-P25. The mechanical activation increased the absorption in the visible range of TiO2-P25 and the photocatalytic activity of a-FeOOH– TiO2. …”
