Summary: Photocatalytic reduction of CO2 into valuable hydrocarbon fuels is a green way to solve the energy problem and achieve carbon neutrality. This study presents a lead-free halide perovskite-based 0D/2D Cs3Bi2Br9/Bi2WO6 S-scheme heterojunction with superior CO2 photoreduction activity under visible light. The improved photocatalytic performance can be attributed to the tight 0D/2D structure and S-scheme charge transfer pathway, which shortens transmission distance of photogenerated carriers and boosts efficient separation and transfer of the carriers. This work provides insights into potential lead-free perovskite-based photocatalysts for achieving carbon neutrality.

Summary: In this study, a series of 0D boron carbon nitride quantum dots (BCNQDs) modified 2D Bi4O5I2 (0D/2D Bi4O5I2/BCNQDs) composites were synthesized and applied to photodegradation of tetracyclines (TCs), including tetracycline (TC) and oxytetracycline (OTC). The optimal composite Bi4O5I2/BCNQDs (1 mL BCNQDs) exhibited the highest photocatalytic performance, with degradation rate constants for TC and OTC being 4.95 and 2.17 times higher than that of Bi4O5I2, respectively. This can be attributed to the narrow bandgap property of Bi4O5I2 as an electron acceptor, and the oxygen-containing functional group with negative charge on BCNQDs promoting the formation of photoexcited holes for effective carrier separation.

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.
