Facet effect of TiO2 nanostructures from TiOF2 and their photocatalytic activity

Self-Cleaning Polyester Fabric Prepared with TiOF2 and Hexadecyltrimethoxysilane

“…With UV irradiation, aT exhibited the highest MB decomposition by photocatalytic degradation even after 30 min, and 95.1% of the MB stained on this fabric was decomposed after 12 h. However, with sunlight irradiation, aT exhibited the lowest level of MB decomposition with 86.8% decomposition, whereas 450TF, 500TF, and 550TF exhibited 100, 96.3, and 97.3% decomposition, respectively, after 12 h. Therefore, the photocatalytic self-cleaning properties of those samples were superior to the commercial anatase TiO 2 treated samples. This is because anatase TiO 2 only utilizes UV light, whereas TiOF 2 utilizes both UV and visible light for the photodegradation of MB [ 39 , 40 , 41 ]. As already mentioned, UV makes up only a small portion of sunlight.…”

Application of Spinel and Hexagonal Ferrites in Heterogeneous Photocatalysis

“…Since water purification from organic pollutants remains the most investigated application of the magnetic photocatalysts, these details, as well as the possible factors that affect them, are considered as crucial for further studies to better understand the interactions between hexaferrites, other photocatalysts, and pollutants. Moreover, the surface structure of the magnetic materials is usually not considered, though many reports on other photocatalysts have proven how important it is for efficient photocatalytic performance [111,144]. In this regard, surface-based studies of such materials are highly recommended as another direction for further research.…”

Preparation of F-doped H2Ti3O7-{104} nanorods with oxygen vacancies using TiOF2 as precursor and its photocatalytic degradation activity

“…08-0060) indicating that the cubic TiOF 2 was successfully prepared. 24,34 Fig. 1b shows the XRD patterns of the samples obtained from the TiOF 2 precursor aer alkali hydrothermal and ion-exchange treatment.…”

“…30,31 Interestingly, TiOF 2 can be transformed into F-doped TiO 2 under certain hydrothermal conditions. [32][33][34][35] Therefore, it is possible to synthesize K 2 Ti 3 O 7 under alkaline hydrothermal conditions with TiOF 2 as the source of titanium and uorine, and KOH as the promoter. Through simple HCl ion-exchange, K 2 Ti 3 O 7 is further transformed into F-doped H 2 Ti 3 O 7 nanorods with oxygen vacancies.…”
