Summary: The performance of the Mn-Na2WO4/SiO2 catalyst for oxidative coupling of methane (OCM) has been attributed to crystalline phases that are not present at reaction temperatures. The evolution of W and Mn sites structure was monitored, showing phase transitions and changes in bond order with temperature. Steady-state experiments demonstrated that Mn3+ sites are more active in methane activation.

Summary: The study successfully validated a model for simulating the direct synthesis of dimethyl ether (DME) in a packed bed membrane reactor (PBMR) using a LTA zeolite hydrophilic membrane. Experimental runs showed that the model accurately predicted the molar fractions of compounds in the reaction medium and their evolution over time. The partial separation of H2O from the reaction medium in the PBMR led to higher DME yield, CO and CO2 conversions compared to systems without membrane.

Summary: This study investigates the structure and promotional effect of Mn in supported Mn-Na2WO4/SiO2 catalysts for the OCM reaction. Multiple in-situ characterization studies reveal that the catalyst possesses crystalline Na2WO4, Mn2O3, and SiO2 along with surface MnOx and Na-WOx sites. Under the OCM reaction environment, the Na2WO4 phase melts and the Mn2O3 phase reduces, while the surface MnOx and Na-WOx sites remain stable. The stable MnOx species interact with the molten Na2WO4 phase and surface Na-WOx sites during the OCM reaction.

Summary: The study on gamma-LiAlO2-Ag cermets integrated in a packed-bed membrane reactor demonstrates their potential for selective separation of CO2 and O2 at high temperatures, and simultaneous syngas production through oxidative CO2 reforming. The obtained cermets show excellent wettability properties against molten carbonates, corrosion resistance, and superior thermal stability, contributing to their performance in gas separation and syngas production. Long-term permeation tests also confirm the membrane's excellent thermal and chemical stability under continuous reaction conditions.

Summary: This study experimentally compares the performance of a packed bed membrane reactor (PBMR) and a conventional packed bed reactor (PBR) for CO2 conversion to dimethyl ether (DME). The PBMR outperforms the PBR in most conditions, with improvements in CO2 conversion and DME yield. Higher sweep gas-to-feed ratios increase water removal and improve PBMR performance, but result in the removal of other products. Higher temperatures selectively enhance the rWGS reaction but reduce DME yield due to methanol loss. Higher transmembrane pressures are not beneficial for PBMR performance. Reactor models developed in previous studies accurately describe the performance of both reactors and can be used for further optimization and simulation.

Summary: In this study, the switching voltage technique was used to efficiently exfoliate graphite in eutectic molten salts. The exfoliated graphene samples exhibited high production yields, low ID/IG ratios, and good electrical conductivities. Compared to constant voltage exfoliation, the switching voltage technique produced smoother graphene flakes with less agglomeration, crumbling, and wrinkling. Characterization analysis confirmed the smaller crystallite size, lower thickness, and higher quality and purity of the exfoliated graphene prepared using the switching voltage technique.

Summary: The desire to improve photocatalytic activity is increasing, especially in semiconductors. Porous photocatalysts have been synthesized to improve surface area and reduce recombination of electron-hole pairs. This paper reviews recent works on porous photocatalysts, with a focus on synthesis and fabrication methods. The topotactic transition technique is the best method for metal oxide porous photocatalysts, while self-organizing blocks are the best method for polymeric porous photocatalysts, especially for growing and fixing 1D semiconductor nanomaterials on 3D and 2D semiconductors on 2D. The hard template method allows for better control of particle shape and size, but the template removal is non-ecofriendly, making the soft template method more favorable. The etching method, on the other hand, is suitable for fabricating porous photocatalysts through a membrane by utilizing the electrical charge created by moving electrons in the electrolyte as a driving force.

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.
