Abstract
Solid-state process of introducing oxygen vacancies into the structure of TiO2 and ZnO particles was studied. The phase transformations of metal oxides throughout the process were examined by X-ray diffraction (XRD). The influence of the loaded mechanical stress on the band gap was studied by diffuse reflectance spectroscopy (DRS). Mechanism of elimination of oxygen atoms from the surface of the oxides by co-milling with polyolefins, which can lead to creation of more effective materials for waste water treatment, was proposed.
