Summary: ZnFe2O4 (ZFO) composites with TiO2 (anatase, rutile) were synthesized and investigated for photocatalytic reduction of CO2 to CO. ZFO was obtained through precipitation from zinc and iron nitrates(V) precursors, followed by hydrothermal treatment, and its physicochemical properties were characterized. The results revealed that the ZFO/TiO2 systems formed type-I heterojunctions, which led to enhanced photoactivity of the composites. Furthermore, choosing anatase as the TiO2 polymorph favored higher yields of CO production.

Summary: This study introduces photocatalysis as a promising technology to remove antibiotics from water, and develops In2.77S4/Ti3C2 composites for photocatalytic degradation of tetracycline (TC). The composites show enhanced photocatalytic degradation efficiency under visible light illumination, reaching a maximum of 89.3% in 90 minutes. The improved efficiency is attributed to the tight combination of In2.77S4 and Ti3C2 at the interface, forming a heterojunction. Holes are identified as the main active species during the degradation process.

Summary: The novel ternary BiOBr/g-C3N4/Ti3C2Tx (BCT-x) hybrids were successfully prepared via the in-situ construction method, and showed improved photocatalytic degradation performance for Tetracycline Hydrochloride (TC-HCl) and Rhodamine B (RhB). The BCT-5 exhibited vintage photocatalytic activity for both TC-HCl and RhB. LC-MS analysis showed that TC-HCl could be degraded into smaller and non-toxic substances by BCT-5. This study provides guidance for advancing the application of photocatalytic technology in water pollutant degradation.

Summary: This study demonstrates the double-edged sword effects of the methylammonium chloride (MACl) additive on the properties of methylammonium lead mixed-halide perovskite (MAPbI(3-x)Cl(x)) films and perovskite solar cells (PSCs). Undesirable morphology transition occurs in MAPbI(3-x)Cl(x) films during annealing, affecting the film quality, optical properties, structure, defect evolution, and power conversion efficiency (PCE) of related PSCs. A post-treatment strategy called FAX (FA = formamidinium, X = I, Br, and Ac) is developed to inhibit morphology transition and suppress defects, resulting in a champion PCE of 21.49% and impressive stability.

Summary: The abuse of tetracycline and other drugs leads to the accumulation of antibiotics and their metabolites in the water system, posing a threat to human life. This study developed a novel Z-scheme heterojunction for efficient photocatalytic degradation of tetracycline using a Bi12O17Br2/(001)-TiO2 catalyst. Unlike traditional Z-scheme heterojunctions, (001)-TiO2 acts as an electron syringe, promoting special charge transfer and enhancing the efficiency of electron hole pair separation and transfer. The stacked layered structure of the catalyst also increases the specific surface area, allowing for better pollutant adsorption and increased reactive active site. The degradation efficiency of the BT5 catalyst for tetracycline solution reached 99.76% in 50 min, and it maintained a high degradation rate of 93.50% after four cycles. This study provides new design ideas for the removal of antibiotic pollutants using novel Z-scheme structures.

Summary: Water is considered an inhibitor of CO oxidation. The practical application of CO oxidation is investigated by coupling Au nanoparticles and defective CuO to form metal-support interactions and oxygen vacancies. The introduction of Au creates new CO adsorption sites, solving the competitive adsorption problem with H2O and O2. The coupling of metal-support interactions and oxygen vacancies enhances the catalyst's ability and oxygen activation and migration. Au-CuO exhibits stable CO oxidation at room temperature under humid conditions. Theoretical calculations confirm the competitive adsorption and the influence of metal-support interactions and oxygen vacancies on catalyst performance, explaining the mechanism of water resistance in CO catalytic oxidation.
