New hybrid TiO₂-based materials were obtained by impregnation of semiconductor with 5,10,15,20-tetrakis(2,6-difluorosulfonylophenyl)porphyrin (F₂POH) and its zinc(II) complex (ZnF₂POH). The efficient immobilization of the porphyrins on the surface of titanium dioxide was obtained due to the presence of -SO₃H functional groups, which interact with the surface of TiO₂. All prepared materials were thoroughly characterized in terms of their morphological, spectroscopic, electrochemical, photochemical and functional properties by diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM) combined with energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), cyclic voltammetry, photoelectrochemistry as well as biological and photocatalytic tests. The modification of TiO₂ with halogenated (metallo)porphyrins allows to improve overall properties of the studied …
