Summary: Evaporation-induced self-assembly method (EISA) is a reliable and efficient technique for synthesizing porous materials. In this study, we successfully prepared hierarchical porous ionic liquid covalent organic polymers (HPnDNH2) for the removal of ReO4- /TcO4- using CTAB-assisted EISA. The CTAB not only acted as a soft template for pore formation, but also induced an ordered structure in the material. The HPnDNH2 showed higher adsorption capacity and faster kinetics compared to 1DNH2, and exhibited outstanding efficiency in removing ReO4- /TcO4- from alkaline nuclear waste.

Summary: In this study, trisphloroglucinol substituted triazine was used as a building block to construct hypercrosslinked polymers for the removal of organic micropollutants from water. These polymers exhibited hierarchical porous structure, high degree of functionality, and good hydrophilicity. The embedded trisphloroglucinol skeletons enabled effective adsorption of various cationic and nonionic organic micropollutants. The adsorption capacity and rate of the polymers were superior to previously reported adsorbent materials. Additionally, the polymers could be easily reused multiple times without a significant decrease in adsorption efficiency, making them suitable for wastewater treatment.

Summary: The synthesis of 2-amino-chromene with high yields (82%) was achieved using basic hierarchical zeolites prepared by surfactant-templating as catalysts in a solvent-free environment. The activity of these hierarchical zeolites is more than double that of their microporous counterparts. These results demonstrate the excellent diffusivity and performance of basic hierarchical zeolites, which can be attributed to their well-developed intracrystalline mesoporosity, highly accessible and strong basic sites.

Summary: Facile and efficient production of ultra-stable metal nanocatalysts based on strong metal-support interactions (SMSI) was achieved through ultrasonication in water at ambient conditions, which generated abundant active intermediates, Ti3+ ions, and oxygen vacancies to induce SMSI overlayer formation. The degree of encapsulation could be controlled by the reducibility of solvents and ultrasonication parameters. This approach can be extended to other metal oxide supports and noble metal nanoparticles, leading to enhanced performance in hydrogenation reactions and CO2 conversion.

Summary: Boosting photocatalytic activity through surface plasmon resonance (SPR) effect was demonstrated as an effective approach. In this study, metallic Bi was deposited in situ on the surface of Bi12TiO20 (BTO). The morphology, light properties, crystal structure, and chemical composition of the Bi/BTO composite were analyzed. The Bi/BTO composite showed increased light absorption and smaller electron transfer resistance. The SPR effect of metallic Bi generated hot electrons to promote the production of more active species, and the formed Schottky junction promoted electron separation, resulting in higher photocatalytic activity. The possible photocatalytic mechanism was also proposed for further development of plasmonic photocatalysts.

Summary: The study found that mesoporous Co3O4 catalyst exhibited excellent catalytic activity for the selective oxidation of aromatic alkanes, particularly the conversion of ethylbenzene to acetophenone with a conversion rate of 42% and a selectivity of 90% at 120 degrees Celsius. Furthermore, it was discovered that mCo(3)O(4) followed a unique catalytic pathway of direct oxidation from aromatic alkanes to aromatic ketones, as opposed to the conventional stepwise oxidation to alcohols and then to ketones. This implied that mCo(3)O(4) had a higher kinetic favorability for the direct oxidation of ethylbenzene to acetophenone compared to non-selective oxidation on commercial Co3O4.

Summary: High-capacity cathodes (LiNi0.8Mn0.1Co0.1O2, NMC811) have the potential for vehicle electrification due to their high gravimetric energy density, but their electrochemical performance depends on the stability of the cathode electrolyte interphase (CEI). A conformal LiF layer formed on the NMC811 electrode surface through an in situ ion-exchange metathesis process improves the electrochemical performance by stabilizing the CEI. This finding could pave the way for enhancing the electrochemical performances and cycling stability of high-capacity cathodes by reengineering the CEI.

Summary: Developing a powerful bifunctional catalyst is crucial for achieving future carbon neutrality by reducing energy consumption in the chemical industry. This study synthesizes mesoporous zeolite-encapsulated palladium nanoparticles (Pd@meso-ZSM-5) using emulsification-demulsification and dry-gel transformation methods, which exhibit remarkable catalytic performance in the one-pot multiple tandem reaction of cyclic ketones to bicyclic alkanes. Unlike traditional two-step synthesis routes, Pd@meso-ZSM-5 efficiently produces bicyclic alkanes instead of monocyclic alkanes, due to the sufficient space for large molecular intermediates provided by mesoporosity and the promoting effect of the acid-Pd interface on intermediate conversion.

Summary: The methylation of imidazolium-based room temperature ionic liquids (RTILs) paired with [Tf2N](-) anion results in an unexpected increase in viscosity, while the viscosity decreases when the methylated imidazolium is paired with [B(CN)(4)](-) anion. The compensated Arrhenius formalism (CAF) is used to study the viscosity observations, focusing on the activation energy and entropy of activation. The results show that the activation energy increases with methylation for [Tf2N](-), but decreases for [B(CN)(4)](-).

Summary: As a new type of metal-free carbon catalyst, sp(3)@sp(2)-hybridized bucky nanodiamond (ND) shows competitiveness in oxidative reactions compared to traditional metal catalysts. However, its application in reduction reactions has been rarely studied and the underlying mechanism remains unknown. In this study, a series of sp(3)@sp(2)-hybridized bucky ND is developed to catalyze the reduction of 4-nitrophenol to 4-aminophenol, achieving a satisfactory metal-free catalytic performance and revealing the factors influencing the reaction activity. The oxygen functionality and sp(3)/sp(2) hybridized carbon ratio are identified as important factors. The similarity between carbon catalyzing reduction and oxidation reactions may provide a unified concept for redox reactions with carbon catalysts.
