Summary: Biochar obtained from pyrolysis of anaerobic sewage sludge without pretreatment can be effectively used for PI activation, with the best activation achieved at 800 degrees C. The activation of PI is highly pH-dependent, showing the highest AO7 removal rate at pH 3.0. The SBC-800/PI system has demonstrated anti-interference capacity with common wastewater components and can be reused, with singlet oxygen production and electron transfer being the dominant AO7 oxidation mechanisms.

Summary: By synthesizing rod-type graphitic carbon nitride (NCN), a highly selective production of singlet oxygen can be achieved compared to bulk graphitic carbon nitride (BCN). NCN exhibits higher surface area and surface oxygen adsorption ability, resulting in increased production of O-1(2) under photo-excitation, along with higher recombination efficiency and longer e(-) decay time, showing superior performance in ATZ removal.

Summary: The study aims to achieve a stable graphitic carbon nitride (g-C3N4)/cobalt ions/eosin Y nanohybrid with improved photocatalytic performance through interfacial implantation of cobalt ions. The optimal nanohybrid embedding 5.0 wt.% cobalt ions demonstrated significantly higher activity for H-2 production and exhibited synergistic interaction between g-C3N4/cobalt ions and EY. The photocatalytic mechanism was found to involve efficient inhibition of charge recombination due to strong interfacial interaction in the nanohybrid, offering a potential method for fabricating other efficient heterogeneous photocatalysts.

Summary: In this study, a porous carbon catalyst (Co1(MgO)1/C) was successfully synthesized and used to activate PMS for removing metronidazole (MNZ) from water. The Co1(MgO)1/C exhibited excellent catalytic performances for MNZ removal in various pH and water environments. Characterization and calculations showed that Co1(MgO)1/C possessed a high concentration of oxygen vacancies (OV = 51.3%), which induced the triple degradation pathway of MNZ in the Co1(MgO)1/C-PMS systems. The study provides new insights into the directional regulation of non-radical degradation pathways of pollutants.

Summary: The rational design of Ti3C2Tx MXene-derived TiO2-based photocatalysts with broad light absorption and efficient charge separation for antibiotic degradation has attracted attention. However, the effects of oxygen vacancies and high work function O-terminated Ti3C2 on light absorption and photocatalytic activity are controversial. In this study, Ti3C2Tx-derived TiO2/Ti3C2Tx photocatalysts were regulated to reveal the contribution of different components. The photocatalyst with oxygen vacancies and carbon dopants showed superior performance in tetracycline hydrochloride degradation.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

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.
