Summary: In this study, the decomposition mechanism of ammonium perchlorate (AP) on graphitic carbon nitride (g-C3N4) catalyst was investigated using density functional theory calculation. The main decomposition pathway of AP was found to be HClO4 -> ClO3- -> ClO2- -> ClO- -> Cl-. Additionally, the oxidation of g-C3N4 surface weakened its catalytic capacity for AP decomposition but enhanced its catalytic capacity for the adsorption and dehydrogenation of NH3.

The optimized 15%-g-C3N4/Bi5O7I exhibited efficient degradation of tetracycline under visible light irradiation, attributed to the generation of photo-induced h+ and O2•- radicals. The migration of photo-induced h+ and e- between g-C3N4 and Bi5O7I was investigated, and the degradation pathways and toxicological simulation of tetracycline were evaluated. The composite also demonstrated good stability and reusability, making it a promising photocatalyst for practical applications.

Summary: Constructing S-scheme heterojunction catalysts can be challenging due to the separation of photogenerated electron-hole pairs. In this study, sulfur-doped g-C3N4 and BiOBr materials were synthesized to form an S-g-C3N4/BiOBr S-scheme heterojunction, which establishes a strong internal electric field for efficient separation of photogenerated electron-hole pairs. The study also found that the visible light irradiation of BiOBr generates a large number of photogenerated holes, which oxidize and activate H2O to achieve deep oxidation mineralization.

The WO3_x successfully removed 95.1% of U(VI) at pH 5, with 79.9% being transformed to U(IV) for reductive immobilization. Compared to conventional WO3, WO3_x exhibited narrower band gap energy, higher charge carrier separation, and faster transfer rates, attributed to its construction of oxygen vacancies.

Summary: This study systematically investigated the changes in characteristics and composition of dissolved organic matter (DOM) under UV/PAA treatment, as well as the underlying mechanisms. UV/PAA treatment significantly reduced the aromaticity, apparent molecular weight, and fluorescent abundance of DOM, while producing more oxidized and saturated compounds. The reactive species (.OH and CH3C(O)O./CH3C(O)OO.) play a primary role in DOM changes, but with differences in reaction selectivity and mechanisms.

Summary: The continuous presence of organic pollutants in industrial wastewater poses a significant threat to human health, necessitating urgent and effective treatment. Photocatalytic degradation technology, specifically the use of TiO2 photocatalysts, provides a viable solution for the removal of organic pollutants. However, the limited absorption of visible light by TiO2 hinders its full utilization. To address this issue, the study developed an environmentally friendly synthesis of Ag-coated on micro-wrinkled TiO2-based catalysts, enabling extended absorption of visible light. The synthesized C/F-Ag-TiO2 composite exhibited a significantly lower band gap energy and achieved a remarkable degradation rate under visible light, making it a promising candidate for highly efficient environmental remediation.

Summary: The catalytic activity of Fe-NxC4-x sites with different coordination environments was predicted through theoretical calculations. Substituting N with C to coordinate with Fe atom resulted in inferior Fenton-like catalytic efficiency. Three configurations of Fe-SACs (Fe-N2C2, Fe-N3C1, and Fe-N4) were fabricated and showed that optimized Fe-NxC4-x coordination environments significantly promoted Fenton-like catalytic activity. The coordination dependency of Fe-SACs was also observed in terms of catalytic stability and actual hospital sewage treatment capacity. This strategy of local coordination engineering provides an example of how to modulate SACs with well-regulated coordination environments to maximize their catalytic efficiency.

Summary: The study focuses on the research hot topic of effectively degrading organic dye pollutants in water. CexZryO2 nanocomposites with different ratios of niobium and zirconium were synthesized using a non-stoichiometric and hydrothermal method, and their performance in the photodegradation of organic dyes was examined. By analyzing the band gap energy and specific surface area through solid-state ultraviolet analysis, the factors influencing the catalytic rate of the catalyst in the photocatalytic degradation of methylene blue (MB) were investigated. The highest degradation efficiency for MB, reaching 99.04% within 120 minutes, was achieved with a Ce/Zr molar ratio of 9 : 1 among the CexZryO2 nanocomposites series.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
