Summary: This work systematically investigates the doping of sulfide ions (S2-) on photoactive MIL-53(Fe) and evaluates its performance. The study found that doping can influence the optical band-gap energy of materials, but this does not always lead to improved performance in photocatalytic reactions, especially for hybrid materials like Metal Organic Frameworks (MOFs). By varying the percentage of dopant in the reaction mixture, the study explored the effects of doping on the structural conformations and optical properties of MIL-53(Fe), demonstrating changes in band-gap energy and electron cloud expansion. The best performance in terms of MB degradation was observed for 1% S doped MIL-53(Fe) and the material showed stability even after multiple cycles, indicating potential for practical applications.

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: This study found that pollutants containing phenolic moiety can greatly enhance the efficiency of the Fe(III)/H2O2 system without catalyst in degrading pollutants. Kinetics analysis revealed the self-catalytic degradation of the pollutants, with the best performance observed at pH 4.0. Spectroscopic measurements and theoretical calculations revealed a previously overlooked self-catalytic mechanism involving the formation of a yellow-colored high-spin P-Fe(III)-OOH complex, which subsequently converts to Fe(II). The oxidation of phenolic moiety generates hydroquinone, which also facilitates the cycling of Fe(III)/Fe(II) and the generation of hydroxyl radicals responsible for efficient decontamination.

Summary: This study investigated the kinetics and mechanisms of the reactions between Feaq II and PMS or PDS at different pH values, as well as the influence of bicarbonate (HCO3-). The results showed that FeaqIV was the dominant oxidizing species in the absence of HCO3-. In the presence of environmentally relevant concentrations of HCO3-, carbonate radical anion (CO3 center dot-) became the dominant reactive species. These findings provide insights for advancing persulfate-based advanced oxidation processes (AOPs) in oxidizing pollutants in natural water.

Summary: We report the successful synthesis of 2D/2D ZnIn2S4/Ti3C2 nanocomposites by a facile one-step hydrothermal method, and evaluated their photocatalytic hydrogen evolution performance under visible light irradiation. The optimal photocatalytic activity was achieved at 5% Ti3C2, which was significantly higher than that of pure ZnIn2S4, ZnIn2S4/Pt, and ZnIn2S4/graphene. The enhanced activity is attributed to the close interfacial contact between Ti3C2 and ZnIn2S4 nanosheets, which enhances the transport and separation of photogenerated carriers. This research introduces a novel approach for the synthesis of 2D MXenes for photocatalytic hydrogen production and expands their application in energy storage and conversion.

Summary: In this study, hierarchical CdS/Co@C nanostructures were synthesized and evaluated for their adsorption and photocatalytic efficiency in degrading ciprofloxacin under visible-light irradiation. The prepared material effectively suppressed CdS self-agglomeration and enhanced visible-light absorption, resulting in significantly higher photodegradation rate compared to CdS alone. The enhanced performance was attributed to rapid electron-hole pair separation and efficient electron transfer between CdS and Co@C. The study provides new insights into the design of novel photocatalysts for organic pollutant degradation in water.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
