Summary: Electrocatalytic oxidation (ECO) is a highly efficient and environmentally friendly method for water treatment. This study focuses on the preparation of high-performance anodes with long service lifetimes. Porous Ti/RuO2-IrO2@Pt, Ti/RuO2-TiO2@Pt, and Ti/Y2O3-RuO2-TiO2@Pt anodes were fabricated using modified micro-emulsion and vacuum impregnation methods. These anodes exhibited large electrochemically active areas and long service lives. The Ti/Y2O3-RuO2-TiO2@Pt anode showed the highest degradation efficiency for tetracycline and consumed the lowest energy.

Summary: The electrocatalytic properties of Ti/RuO2-SnO2 and Ti/RuO2-IrO2 anodes in different electrolytes were studied for aniline degradation. Ti/RuO2-SnO2 showed higher activity in Na2SO4 electrolyte, while Ti/RuO2-IrO2 was more effective in NaCl electrolyte. The presence of Fe2+ can decrease TOC removal efficiency, especially for Ti/RuO2-SnO2.

Summary: This study investigated the application of a reverse electrodialysis reactor (REDR) in treating synthetic methyl orange (MO) dyeing wastewater. The effects of operation parameters on the chemical oxygen demand (COD) removal efficiency were explored and a mathematical model was developed to predict the variation of COD removal efficiency with treating time under different conditions. The results showed that increasing the fluid velocity and rinse solution flowrate improved the COD removal efficiency and reduced the total energy consumption of the REDR.

Summary: In order to optimize the energy-consuming cobalt electrowinning process and satisfy the increasing demand for pure cobalt, the effects of additives (SLS, H3BO3, and CoCl2) on current efficiency were studied using cyclic voltammetry. The appropriate concentration range of additives for the electrowinning design study was determined. Through electrowinning tests, it was found that the addition of 0.05 g/L SLS, 10 g/L H3BO3, 50 g/L Na2SO4, and 1 g/L CoCl2 achieved a current efficiency of 96% and an energy consumption of 1.95 kWh/kg, resulting in a smooth metallic deposit without defects. Higher concentrations of SLS led to the formation of compact structures, while higher concentrations of H3BO3 lightened the deposits.

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.
