Summary: A series of tin (Sn)-doped titania (TiO2) composites were prepared by electrospinning and calcination. The effect of dopant amounts and calcination temperatures on the composition, morphology, and photocatalytic activity of the composites was evaluated. The ([1.5%]Sn:TiO2) composite sintered at 500°C showed remarkable photocatalytic activity with a removal efficiency of about 100% and a rate constant of 9.685 x 10-2 min-1. Structural investigations were conducted to explain the photocatalytic activity towards water decontamination.

Summary: A novel Z-scheme ZnSnO3/Bi2WO6 (ZSO/BWO) piezo-photocatalyst with a synergistic polarized electric field was synthesized. The optimized 1% ZSO/BWO showed exceptional piezo-photodegradation efficiency and mineralization of diclofenac (DCF) under combined ultrasound and light, surpassing the results using ultrasound or light alone. The enhanced activity of the ZSO/BWO composite was attributed to increased absorption, improved charge transfer, Z-scheme heterojunction, and strong surface contact between ZSO and BWO. The Z-scheme mechanism of ZSO/BWO composites was studied and confirmed using radical capture and electron spin resonance technology. The intermediates and possible degradation pathways of DCF on ZSO/BWO composites were analyzed by liquid chromatography-mass spectrometry and DFT, providing insights into the mechanisms of photocatalytic degradation.

Summary: The purpose of this study was to investigate the effect of photocatalytic degradation using nitrogen and tungsten co-doped titania (TiO2) nanoparticles, which are cost-effective and environmentally friendly. The synthesized nanoparticles were analyzed using various techniques, including spectroscopy, microscopy, and spectrometry. The co-doping of metal and non-metal enhanced the photocatalytic properties of the TiO2 nanoparticles, particularly in the visible region. This resulted in improved absorption of visible light and reduced recombination of electron-hole pairs, leading to accelerated photodegradation. The bandgap of the titania nanoparticles was reduced after efficient doping, enabling the photodegradation of malachite green under visible light illumination. The results of photocatalytic degradation were confirmed using spectroscopy and high-performance liquid chromatography coupled with mass spectrometry.

Summary: The degradation of diclofenac (DCF) by Fe2+/chlorine and Fe2+/PMS processes was investigated in this study. The optimal conditions for DCF degradation were determined by evaluating the influence of pH, Fe2+, and oxidant dosage. The results showed that under the optimized conditions, the degradation efficiencies of DCF using Fe2+/chlorine and Fe2+/PMS processes reached 94.2% and 79.7% within 10 minutes, respectively. The degradation products and pathways were identified, and it was found that Fe2+/chlorine could control the formation of chlorinated disinfection byproducts (DBPs).

Summary: This study investigates the photocatalytic degradation of diclofenac using hybrid materials composed of graphitic carbon nitride (g-C3N4) and titanium-metal organic framework (NH2-MIL-125) in various mass proportions. The hybrid materials exhibited higher photocatalytic activity than the individual components, with a 50:50 MOF:g-C3N4 ratio yielding the highest conversion rate, completely eliminating diclofenac in 2 hours. Identification of by-products species allowed for proposing a degradation pathway under the experimental conditions.

Summary: In this study, spent bleaching earth (SBE) was modified and loaded with zero-valent iron (nZVI) to remove diclofenac (DCF) from water bodies. The removal efficiency of DCF reached a maximum of 87.0% under optimal conditions. Four possible degradation paths were inferred based on detected reaction intermediate products. The toxicity assessment showed that CTAB-SBE@C-nZVI can gradually dechlorinate DCF and reduce its toxicity. This study demonstrates the potential and environmental friendliness of using CTAB-SBE@C-nZVI for waste treatment.

Summary: This study investigated the transformation mechanisms, kinetics, and toxicity of diclofenac in the persulfate oxidation process. The results showed that the reactivity of the benzylic position of diclofenac was higher than that of the chlorinated aromatic ring, indicating that the hydroxyl radical and persulfate radical were more likely to react at the benzylic position. Kinetic calculations revealed a positive correlation between degradation rate constants and temperature. Furthermore, the toxicological analysis demonstrated a reduced toxicity level in most degradation products, with the hydrolysates remaining toxic.

Summary: Biochar was obtained from spent malt rootlets through pyrolysis under limited oxygen supply and further activated by mixing with KOH and pyrolyzing again at high temperature. The activated biochar showed a total specific surface area of 1148 m(2) g(-1) and a micropore specific surface area of 690 m(2) g(-1). When used as an electrode in combination with a photoelectrochemical cell, the biochar electrode acted as a supercapacitor with a specific capacity of 98 Fg(-1), capable of storing and utilizing charges generated by the cell under both illuminated and dark conditions. Additionally, the same electrode exhibited electrocatalyst properties as an air-cathode, enabling oxygen reduction.

Summary: Pyrolysis of lemon stalks at 850 degrees C under limited oxygen produces highly active and selective biochar that can activate persulfate ion and oxidize sulfamethoxazole (SMX). The biochar consists mainly of carbon and oxygen atoms, with calcium and potassium as the most abundant minerals. It has a moderate specific surface area of 154 m(2) g(-1) and contains carbonate species, possibly in the form of calcium carbonate. In ultrapure water, complete degradation of 0.5 mg L-1 SMX can be achieved within 20 minutes using 500 mg L-1 sodium persulfate (SPS) and 100 mg L-1 biochar. The biochar remains stable for at least five cycles and shows potential as a sustainable, metal-free catalyst.

Summary: The electrochemical oxidation of the breast-cancer drug anastrozole has been studied in this work, with factors such as current density, pH, ANZ concentration, and supporting electrolytes being evaluated. ANZ removal was achieved at a certain initial concentration, with the degradation following pseudo-first-order kinetics. The addition of chloride was found to have a positive effect within a certain range, but detrimental effects above a certain concentration. The presence of bicarbonate or organic matter had a slightly negative effect on the process.

Summary: The pursuit of low-cost, high-efficiency co-catalysts without noble metals in photocatalysis has attracted significant interest in recent years. In this study, a series of cobalt phosphide (CoP 0.125-1.00 wt.%) promoted bismuth vanadate (BiVO4) photocatalysts were synthesized and characterized. The efficiency of these photocatalysts was investigated for sulfamethoxazole (SMX) degradation under simulated solar light irradiation. The results showed that the deposition of a small amount of CoP on BiVO4 enhanced SMX degradation.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

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.
