Summary: In this study, a mesoporous α-Fe2O3-NPs@AgVO3-NRs (0D/1D) Z-scheme semiconductor photocatalytic system was prepared for energy production and environmental remediation applications. The α-Fe2O3-NPs and AgVO3-NRs were synthesized separately and then combined to form a heterojunction. The resulting α-Fe2O3@AgVO3 nanocomposite exhibited excellent visible light trapping capability and enhanced charge separation, resulting in high photoreduction efficiency and photocurrent density. The formation of the Z-scheme heterojunction facilitated photogenerated charge carrier migration and separation, leading to efficient photo-redox reactions. Overall, this work provides a feasible strategy for synthesizing binary synergistic catalytic systems for photo(electro)chemical applications.

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.
