Summary: In this study, NCNT/ZIF-8 nanocomposite was prepared via the hydrothermal method for providing clean fuels through desulfurization. The nanocomposite showed excellent adsorption capacity for DBT, attributed to the synergistic effects of NCNT and ZIF-8, the presence of basic groups in NCNT structure, and high surface area and pore volume. The regenerated NCNT/ZIF-8 maintained good performance even after 3 adsorption-desorption cycles with almost unchanged adsorption capacity.

Summary: Given the characteristics and risks of ammonia, the removal of ammonia is crucial for industrial production and environmental safety. This study modified viscose-based activated carbon fiber (ACF) with nitric acid impregnation to enhance its adsorption capacity for ammonia. The results showed that ACF-N-6 significantly increased the surface functional group content without destroying the physical structure of the activated carbon fibers. The highest adsorption capacity of ammonia by ACFs was 14.08 mmol/L at 293 K, which was a 165% increase compared to ACF-raw. The adsorption performance was strongly correlated with the carboxyl group content and relative humidity of the inlet gas. This research contributes to the development of efficient ammonia adsorption systems for industrial production and environmental safety.

Summary: This study investigates the effect of surface modifiers on the catalytic properties and degradation efficiency of a polymeric matrix (CuO/PVA) using three different surfactants: cationic (CTAB), anionic (SLS), and non-ionic (T80). The results show that surface modification significantly enhances the degradation ability of the polymeric CuO, with CTAB-assisted CuO exhibiting a 29% higher degradation rate compared to its unmodified counterpart. The surface characteristics of the catalyst, including particle size, band gap, and morphology, also play a crucial role in the degradation process.

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.
