Highly stable defective TiO2-x with tuned exposed facets induced by fluorine: Impact of surface and bulk properties on selective UV/visible alcohol photo-oxidation

Transformation of novel TiOF2 nanoparticles to cluster TiO2-{001/101} and its degradation of tetracycline hydrochloride under simulated sunlight

“…3f), demonstrating the exposure of {001} facet on the surface of T-4h. 45,49 Compared with the TiO 2 with {001} facet exposure reported by most studies, 48,54 the size of TiO 2 -{001/101} derived from corallike TiOF 2 is smaller. All the above results indicate that the coral-like TiOF 2 can be transformed into cluster TiO 2 -{001/101}.…”

“…The existence of uorine forms -Ti-F-Tiand Ti 3+ species to replace lattice oxygen to form O vs . 45 The formation of Ti 3+ /O vs is an effective and environmentally friendly strategy to improve visible light absorption and pollutant adsorption. Moreover, the existence of O v can form an electron trap, which greatly reduces the composite rate of electrons and holes, thus effectively enhancing the photocatalytic activity of TiO 2 .…”

(Photo)electrocatalytic Versus Heterogeneous Photocatalytic Carbon Dioxide Reduction

“…The defects consumed by CO 2 reduction can be easily regenerated by blowing in an inert gas at a moderate temperature. Furthermore, the oxygen vacancies have the positive effect of inducing a large light absorption capacity by the catalyst [196] …”

Selective Oxidation of Benzyl Alcohol in the Aqueous Phase by TiO2‐Based Photocatalysts: A Review

“…The surface F with negative electricity can trap holes, thereby preventing the charge recombination. Moreover, the formation of anatase (001) facets was promoted in the presence of F, which worked as oxidative sites in the photooxidation [56,57]. Conv., conversion; sel., selectivity.…”
