Preparation of Cu₂O@TiOF₂/TiO₂and its photocatalytic degradation of tetracycline hydrochloride wastewater

Abstract

Cu2O@TiOF2/TiO2 composites with large surfaces were prepared by a hydrothermal method and exhibited excellent activity under simulated solar light, showing high efficiency for tetracycline hydrochloride photocatalytic degradation, and reusability.

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

“…2a, the TiOF 2 precursor consists of a mixture of cubic and spherical particles with an average size of 280-500 nm (which corresponds to the diameter of the sphere or the side of the cube). Compared with some other results of the prepared TiOF 2 , [35][36][37] the morphology of the precursor obtained in this study is not uniform.…”

The preparation of three-dimensional flower-like TiO2/TiOF2 photocatalyst and its efficient degradation of tetracycline hydrochloride

“…4, according to the classication of IUPAC, all samples show a typical IV type adsorption desorption isotherm with H3 type hysteresis ring, which represents that the sample has a mesoporous formation and matches the image presented by SEM. 38 According to the adsorption-desorption isotherm, the specic surface areas of pure TiOF 2 , TiO 2 , and 8-TF are 4.8, 53.6, 67.74 m 2 g À1 , respectively. The specic surface area of the composite photocatalyst is signicantly higher than that of TiOF 2 and TiO 2 .…”

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.…”
