Summary: A nanocomposite consisting of CoFe-layered double hydroxides grown on graphitic carbon nitride nanosheets (CoFe-LDH/g-C3N4) has been successfully synthesized and exhibits significant photocatalytic activity for the degradation of tetracycline. The enhanced performance is attributed to the intimate interfacial contact, enlarged surface area, broadened absorbance range, and improved electron transfer. This study demonstrates the feasibility and potential application of the nanocomposite for the removal of tetracycline from contaminated water.

Summary: An innovative g-C3N4-TiO2@CsPbBr3 composite catalyst was prepared and demonstrated to have enhanced photocatalytic performance for tetracycline hydrochloride degradation. The catalyst exhibited increased light-harvesting capability and more efficient charge carrier separation, leading to a degradation rate of 75.6% in 120 min, which was 2.30 and 2.03 times higher than TiO2@CPB and pure g-C3N4, respectively. The study also identified O-2(-) as the dominant active specie in the photocatalytic degradation process and proposed a possible photocatalytic mechanism.

Summary: Rutile TiO2 microspheres and WO3 nanosheets were synthesized via hydrothermal treatment, and a WO3/TiO2 heterojunction was prepared with different mass ratios using physical mixing. Photocatalytic performance was evaluated using the degradation of Rhodamine B dye under simulated sunlight. The WO3/TiO2 with a mass ratio of 1:5 showed the highest photocatalytic efficiency of 91.5% within 60 minutes. Holes (h(+)) and superoxide radical (center dot O-2(-)) were found to play key roles in the degradation process. The unique type-II WO3/TiO2 heterojunction extended the light absorption range and improved photocatalytic activity.

Summary: Developing facile photocatalysts with high activity and stability is a promising strategy for tetracycline degradation. The well-designed photocatalysts prepared via facile Ar atmosphere calcination with H-titanate nanotubes as precursors showed excellent visible light behavior by utilizing suitable oxygen vacancies (Ti3+ sites) as charge carrier traps. The efficient photocatalytic efficiency for TC degradation demonstrated significant activity of both h(+) and center dot O-2(-) under visible light irradiation.

Summary: In this study, a multifunctional membrane (TCPP/UiO@SSM) was fabricated for gravity-driven oil-water/seawater mixtures separation and visible-light-driven bacterial inactivation. The membrane demonstrated high permeation flux and separation efficiency, thanks to its rough hierarchical structure and super-wettability. It effectively dealt with viscous oil fouling and demonstrated superior oil-water separation and photocatalytic sterilization performances compared to UiO@SSM. The doping of photosensitive TCPP in UiO-66-NH2 improved hydrophilicity and enhanced photocatalytic activity. This work provides a new platform for water disinfection and treatment of oily wastewater.
