Summary: This study reports the direct electrochemical synthesis of four iron-based MOFs via controlled potential oxidation of dissolved metal cations. It represents the first general route that employs interfacial electrochemistry to alter the oxidation state of metal ions dissolved in solution to directly trigger MOF formation. The reported method is functional group tolerant and broadly applicable to the bulk synthesis or surface growth of a range of MOFs based on metal ions with accessible oxidation states.

Summary: A novel photo-Fenton catalyst FGN with dual Z-scheme heterojunction was successfully prepared and it showed excellent degradation performance towards tetracycline. The optimized preparation conditions and characterization analyses confirmed the successful synthesis of FGN. The experimental results demonstrated that FGN had better light absorption ability, higher separation efficiency of photoelectrons and holes, larger specific surface area, and higher pore capacity compared to other catalysts. The effects of experimental conditions on the degradation performance were investigated and three degradation pathways of tetracycline were proposed. The structural stability and catalytic active sites of FGN were explored by comparing the XRD and XPS spectra. Additionally, the mechanism of the dual Z-scheme heterojunction was proved through various experimental methods.

Summary: MIL-101(Fe)/WS2 catalyst was synthesized using a solvothermal method. The physical and chemical properties of the composite material were studied using various characterizations. The photocatalysis of the catalyst in the degradation of tetracycline under visible light illumination was investigated using persulfate as a cocatalyst. The catalyst showed high efficiency in removing tetracycline, with a removal rate of over 80% within 40 minutes. The material also demonstrated good recycling capability after multiple cyclic experiments. The enhanced performance of the catalyst was attributed to the reduction of photogenerated electron-hole recombination efficiency and the activation of persulfate to produce free radicals.

Summary: Exploring effective photocatalyst for CO2 conversion is a challenge. A heterostructure, Ti3C2 QDs decorated NH2-MIL-101(Fe), was fabricated and exhibited improved CO2 photoreduction activity. The optimal catalyst achieved a CO-evolution rate of 55.7 mu mol h-1 g-1, 2.6 times higher than pristine NH2-MIL-101(Fe), due to extended visible-light response and effective charge separation. Isotope labeling experiment confirmed the production of CO from CO2, and in-situ FT-IR investigated the intermediates and mechanism of photocatalytic CO2 reduction.

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.
