Summary: In this study, the CoyCu3-y-MOF-74 precursor material was synthesized using a cost-effective and environmentally friendly mechanochemical method. The resulting bimetallic Co-Cu oxide catalyst, M-CoyCu3-yOx, showed a high efficiency for the catalytic oxidation of toluene. The effects of calcination temperature and Co/Cu molar ratio on the catalyst's redox properties, catalytic activity, and structural properties were systematically studied. The MCo2Cu1Ox catalyst exhibited complete toluene conversion at 225℃ and with a space velocity of 30,000 ml/(g h). XPS, Raman spectroscopy, EPR, and DRIFTS experiments provided further insights into the catalyst's properties and reaction intermediates. The catalyst also demonstrated excellent durability and water resistance. The green and facile mechanical synthesis of the MOF-74 precursor proved to be beneficial for the design and synthesis of highly efficient mixed metal oxide catalysts for toluene oxidation.

Summary: MOF-polymer mixed matrix catalytic membrane has great potential for continuous flow separation and catalysis. However, scalable fabrication methods to produce ultra-high flux mixed matrix catalytic membranes are still lacking. Inspired by the honeycomb structure, a composite MOF with polymer materials was used to prepare large area MOF-polymer mixed matrix catalytic membranes with a honeycomb structure. The resulting membrane has a large surface area and abundant pore channels, enabling rapid passage of reactants and efficient catalysis. The preparation method can be extended to other porous materials, showing promising catalytic effects.

Summary: In this study, core-shell ZIF-8@RF nanofillers were incorporated into 6FDA-Durene and Pebax 1657 via a physical blending approach to form MMMs, which showed outstanding performance for CO2/CH4 separation due to enhanced interfacial compatibility, CO2 affinity, and the intrinsic characteristics of porous ZIF-8. The CO2 permeability and CO2/CH4 selectivity of the MMMs increased significantly compared to the pristine membrane, and the presence of RF layer in ZIF-8@RF MMMs further improved the CO2/CH4 selectivity. Importantly, both MMMs maintained their excellent separation performance even in the presence of moisture.

Summary: In this study, a novel hollow Fe0/graphitized carbon nanocubes (HFe0/GC) catalyst was prepared for degrading bisphenol A (BPA) by activating peroxymonosulfate (PMS), and compared with a solid Fe0/graphitized carbon (SFe0/GC) catalyst. The introduction of tannic acid helped maintain the catalyst structure at high temperatures, and the HFe0/GC catalyst exhibited significantly enhanced degradation performance when used with PMS. The BPA degradation rate constant (k-1) of HFe0/GC was 3.7 times higher than that of SFe0/GC, with 98% of BPA removed within 8 minutes. Gas chromatography mass-spectrometry (GC-MS) analysis confirmed the presence of both radicals and non-radical species in the HFe0/GC/PMS system, and identified the intermediates of BPA degradation. Doping and etching of a metal-organic framework to obtain modified HFe0/GC may serve as an effective and non-toxic catalyst for advanced oxidation processes (AOPs).

Summary: A facile and sensitive glucose sandwich assay using surface-enhanced Raman scattering (SERS) was developed. Glucose was captured by 3-aminopheyonyl boronic acid (APBA) modified Ag nanoparticles decorated onto a polyamide surface. APBA forms specific cis-diol compounds with glucose molecules avoiding interference by other saccharides and biomolecules in urine enabling its selective detection. AEPO exhibited a distinctive SERS peak in the Raman silent region, thus increasing the sensitivity of the glucose detection to 10(-11) M. The developed SERS assay was reusable and showed potential as a diagnostic tool for glucose sensing in clinical applications.

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.
