Summary: This study explores the constructional modification of Graphitic carbon nitride nanosheet (GCN-ns) with ZnCr layered double hydroxide (ZC-LDH) to enhance its visible light absorption. The incorporation of ZC-LDH onto the surface of GCN-ns improves its photocatalytic abilities, leading to effective degradation of Rhodamine B under UV/vis light irradiation. The self-production of H2O2 on the GCN-ns/ZC-LDH surface accounts for additional hydroxide radical generation, contributing to the improved performance.

Summary: A new NiTi-layered double hydroxide photocatalyst has been developed for the selective conversion of ethane to n-butane. The NiTi-LDH catalyst exhibits a high selectivity and production rate for n-butane, thanks to its rich vacancies and efficient electron-hole separation. Theoretical calculations reveal that ethane is activated on oxygen vacancies of the catalyst surface, favoring C-C coupling rather than C-H cleavage to produce n-butane.

Summary: This study combines efficient charge transfer pathway and precision loading to construct a novel Pd-Cu/TiO2 photocatalyst with high selectivity for methanol production. Loading Pd on Cu species instead of TiO2 facilitates the concentration of electrons on Cu, and the ion exchange method for Pd loading creates more oxygen vacancies, leading to improved visible light absorption and charge separation. In situ FT-IR testing reveals the evolution from CO2 to CH3OH and the critical intermediates involved. This work provides insights into precision loading of Pd and presents a novel design for photocatalysts.

Summary: Photocatalysis technology is a promising strategy to convert CO2 into fuels and mitigate the greenhouse effect and energy crisis. In this study, the Z-scheme Ag/UiO-66@g-C3N4 composites showed improved CO2 photoreduction activity due to their increased specific surface area, strong redox capacity, rapid separation of photoinduced h+/e- pairs, and fast transfer of e-. The CH3OH and CO evolution rates of the composites were 3.09 and 2.40 times higher than those of g-C3N4, respectively. The Quantum yield (QY) of CO and CH3OH for the composites were 0.0217% and 0.0986%. The Ag NPs acted as e- mediator, promoting charge separation, transport, and CO2 reduction ability. This study not only presents a simple method to prepare ternary composites but also demonstrates their efficient photocatalytic CO2 conversion to methanol and CO.

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.
