Summary: In this study, BiOI was surface decorated with multiwall carbon nanotubes (MWCNTs) using a hydrothermal method. The samples were characterized using various techniques, and the results showed that the surface modification with MWCNTs significantly enhanced the photocatalytic activity of BiOI. This enhancement can be attributed to the strong interaction between MWCNTs and BiOI, as well as the excellent conductivity of MWCNTs, which promoted the separation of electron-hole pairs.

Summary: In this paper, oxygen vacancies (OVs) were introduced in Bi4Ti3O12 (BIT) nanosheets to enhance their piezo-photocatalytic performance. Compared to pristine BIT nanosheets, BIT with optimized OV concentration showed excellent piezo-photocatalytic activity, with a 2.2 times enhancement of the degradation rate constant for Rhodamine B (RhB). Density functional theory (DFT) calculations were used to investigate the effect of OVs on adsorption energy and Bader charges, providing insights into the underlying mechanism of OV enhanced piezo-photocatalytic activity. This study contributes to a deeper understanding of the regulation mechanism of OV enhanced piezo-photocatalytic activity and offers new approaches for designing high-performance piezo-photocatalysts.

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.
