Summary: Multilayer strontium-doped TiO2/carbon dots (CDs) materials were prepared using sol-gel-layered carbonization method. The combination of strontium ions, -TiO2, and CDs formed layered structures. The presence of strontium ions resulted in a more positive conduction band position, increasing the visible-light absorption range. Photocatalytic degradation experiments showed a high degradation rate of enrofloxacin, with O-2(-) and -e(-) playing a major role. UPLC-MS analysis detected decarboxylation and defluorination as the possible degradation mechanism.

Summary: In this study, a trace Fe3+ doped TiO2/Bi2WO6 composite photocatalyst was successfully synthesized and showed enhanced photocatalytic activity for toluene degradation. The optimal molar ratio of TiO2 to Bi2WO6 was found to be 1:2. The improved photocatalytic activity was attributed to the extension of carrier lifetime, increase of visible light absorption range, and formation of oxygen vacancies. Hydroxyl radicals and holes were confirmed to be the key reactive oxygen species (ROS) involved in the photodegradation reaction.

Summary: In this study, a visible light driven Pt-doped TiO2 photocatalyst was synthesized, which exhibited superior photocatalytic functionality and degradation efficiency for pharmaceutically active compounds. Pt-doping decreased charge recombination, caused oxygen vacancies, and incorporated Pt into the TiO2 lattice through a two-step process. The catalyst efficiently decomposed CIP under visible light within a short period of time and could be reused with only a slight reduction in degradation efficiency.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
