Summary: Bimetallic oxy(hydroxides) have gained significant interest in water treatment for their potential as highly efficient anion adsorbents. This study focuses on the synthesis of cerium and iron bimetallic oxyhydroxides (Ce:Fe-P's) using microwave-assisted methods. The Ce:Fe-P's exhibit outstanding adsorption capacity and fast adsorption kinetics for arsenic(V), with little interference from pH and coexisting anions. The results suggest that Ce:Fe-P's are a promising adsorbent material for arsenic(V) in water treatment.

Summary: Hot carriers are energetic species that can perform various chemical reactions on the surfaces of nanostructures. Through techniques like surface-enhanced Raman spectroscopy (SERS) and tip-enhanced Raman spectroscopy (TERS), the catalytic properties of bimetallic nanostructures have been found to be influenced by the nature of the catalytic metal and the strength of the rectified electric field on their surfaces. This research sheds light on the mechanisms behind plasmon-driven reactions and has the potential to help develop novel nanostructures with tailored catalytic properties.

Summary: In this study, NaY-zeolites were modified by combining Cu ion-exchange and Na2O or CuO impregnation for adsorptive desulfurization. The results showed that Na2O promoted the adsorption of TBM, while CuO inhibited it. Among the tested samples, the Cu ion-exchanged Y-zeolite containing Na2O showed the most efficient adsorption performance with a 3.97 wt% uptake for TBM, which is 30% higher than that of the Cu ion-exchanged Y-zeolite. The Cu ion-exchanged Y-zeolite containing CuO showed the lowest adsorption ability with a 2.21 wt% uptake for TBM.

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.
