Summary: Copper containing SBA-15 materials were prepared using a simple surfactant-assisted impregnation method. The surfactant in the synthesized SBA-15 played a crucial role in facilitating the distribution of copper species into the channels. Characterization results demonstrated that the surfactant-assisted impregnation method was superior to the conventional impregnation method in obtaining highly dispersed Cu-SBA-15 with isolated copper species and small clusters. These materials exhibited excellent CO oxidation activity and stability due to the finely dispersed Cu species and active sites.

Summary: The highly dispersed ZnS(C)/BiOBr/GO ternary composite was successfully prepared by a two-step hydrothermal method with the assistance of the surfactant CTAB. The photocatalyst exhibited excellent degradation performance for organic dyes and antibiotics, outperforming the individual ZnS(C) and BiOBr photocatalysts. The enhanced photocatalytic activity can be attributed to the reduced aggregation of ZnS and improved dispersion of ZnS by CTAB, as well as the electron trapping effect of GO for carrier separation between ZnS and BiOBr.

Summary: After decades of development, organic photovoltaic semiconductors have made significant progress and have promising application prospects. Compared with traditional semiconductors, the solution method for preparing photovoltaic semiconductors shows the advantages of low cost and convenient preparation. However, the poor solubility of polymers used in the preparation process requires toxic solvents, which have negative effects on the environment and operators. Organic nanoparticles, on the other hand, have been developed as a solution to these issues and have been applied in various fields.

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.
