Summary: This study focuses on the preparation of Cr-doped TiO2 and Cu-doped TiO2 electrodes and their application in the photoanode of a solar redox flow battery (SRFB). The electrodes, prepared through the sol-gel method, exhibit anatase phase structure, with the Cu-TiO2 and Cr-TiO2 electrodes showing greater crystallinity. Tests on the solar flow cells using these materials as photoelectrodes demonstrate that the doping of Cr and Cu improves the efficiency and charging current, with significant increases observed compared to the pure TiO2 electrode.

Summary: In this study, Ce-Mn/TiO2 catalyst was doped with Ho and Sm to enhance its denitration performance at low temperature. Ho doping increased the amount of acid sites and improved low temperature redox property, leading to excellent DeNOx performance. Sm doping resulted in a decline in redox property but increased the acid sites of Ce-Mn/TiO2. Both Ho and Sm doping improved sulfur resistance by inhibiting the adsorption of SO2 and formation of sulfate. Ho-modified Ce-Mn/TiO2 showed better sulfur resistance due to its higher number of surface acid sites.

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.
