Summary: This study elucidates the mechanism of FeOCl-catalyzed perdisulfate activation and highlights the role of surface hydroxyls in facilitating the electron transfer between FeOCl and perdisulfate. Phosphate ions hinder the activity of FeOCl by substituting its surface hydroxyls, demonstrating the essential role of hydroxyls in perdisulfate activation. The study also reveals that the polar surface of FeOCl undergoes hydrolysis, leading to an enrichment of electrons around the Fe site and enhancing the interaction between FeOCl and perdisulfate.

Summary: There has been increasing interest in combining porous metal organic frameworks (MOFs) with conductive carbonaceous materials to enhance catalytic activity. In this study, a simple strategy was developed to synthesize a highly efficient and recyclable heterogeneous catalyst through the pyrolysis of MOFs as sacrificial templates. The introduction of defective sites in the carbon nanotubes (CNTs) precursor significantly improved the charge transfer capability of the composite microcages and the coordination environment of Fe centers. With the assistance of persulfate oxidants, the modulated defects in ZnFe2O4/CNTs-Ar exhibited a 17.5-fold higher reaction rate for Bisphenol A degradation compared to blank ZnFe(2)O(4) microcages. Experimental characterizations indicated that the defective CNTs facilitated the electron transfer from BPA molecules to persulfate, triggering the direct decomposition of pollutants through a non-radical oxidation pathway. This research provides a new strategy for developing high-performance MOFs-derived catalysts for wastewater treatment.

Summary: This study comprehensively investigates the coordination conduct and kinetic modes for the reduction of vanadium(V) by organic nitrogen and sulfur functionalities in different pH conditions. The diffusion of vanadium(V) is controlled by protonated functional groups such as =NH2+, -SH2+, -C--SH+ and oxo-vanadate speciation. The reduction of vanadium(V) to vanadium(IV) is more efficient with -SH as the sole electron donor. The coordination of vanadium(V)/vanadium(IV) species involves parallel orientation with oxygen, nitrogen, and sulfur atoms, revealing a previously unrecognized track. This research proposes a novel tactic for designing an efficient vanadium(V) wastewater treatment system considering water parameters.

Summary: In recent years, biodiesel as a substitute for fossil fuels has gained increasing attention, although its production cost is higher. To reduce the cost, biodiesel has been produced from different feedstock based on local availability, but the feedstock quality limits the quality and efficiency of the transesterification process. The quality of biodiesel depends on fatty acid compositions and physicochemical properties of the oil feedstock, and the use of solid-based catalysts has been preferred due to their reusability and ease of separation. Different catalyst properties and process parameters also influence the transesterification reaction.

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.
