Summary: The mixture of triphenylamine (TPA) and phenyl phenothiazine (PTH) fragments in extended polyimine structures showed varying photocatalytic activities in the degradation of different pollutants under visible light irradiation. Materials with PTH as the sole photoactive unit exhibited the most active photocatalytic performance for polybrominated diphenyl ether-1 and Sudan Red III degradation, while the covalent organic framework containing only TPA was the best photocatalyst for degrading Methylene Blue. These differences were attributed to the versatile abilities of PTH to trigger both photoredox and energy transfer processes, compared to TPA which primarily acts as an energy transfer catalyst.

Summary: In recent years, the increase in global population has led to higher water pollution levels, particularly due to organic pollutants such as phenolic compounds released from industrial effluents. Adsorption is a promising method for removing phenolic contaminants from water, and carbon-based materials, specifically graphene, have shown great potential due to their unique properties. This article focuses on discussing novel synthesis approaches for graphene-based nanomaterials as adsorbents for organic pollutants, with a special emphasis on phenols associated with palm oil milling effluent (POME). The article explores the adsorptive properties, experimental parameters, isotherms and kinetic models, formation mechanisms, and the ability of graphene-based materials as adsorbents for specific contaminants.

Summary: To overcome the collapse of structure and sluggish reaction kinetics of MnO2 in aqueous Zn-ion batteries, researchers prepared Zn2+ doped MnO2 nanowires with rich oxygen vacancies using a hydrothermal method combined with plasma technology. The doped nanowires stabilized the interlayer structure of MnO2 and provided additional specific capacity as electrolyte ions. Plasma treatment optimized the electronic structure and improved the electrochemical behavior of the cathode materials. The optimized Zn/Zn-MnO2 batteries showed outstanding specific capacity and cycling durability, and the H+ and Zn2+ reversible co-insertion/extraction energy storage system of the battery was revealed. The plasma treatment also optimized the diffusion control behavior of the electrode materials. This research proposes a synergistic strategy of element doping and plasma technology to enhance the electrochemical behaviors of MnO2 cathode and provides insights for the design of high-performance manganese oxide-based cathodes for ZIBs.

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.
