Summary: Twelve N-SO3H functionalised ammonium and imidazolium based Bronsted acidic ionic liquids with varying anions were synthesized and characterized. The effects of different cations and anions on the properties of the ILs were studied. The conductivity of the ILs in different solvents was measured and correlated with solvatochromic parameters of the solvents. The polarity of the ILs was studied using fluorescence emission spectroscopy. The electrochemical stability of the ILs in different solvents was determined. Among the four types of anions, CF3COO(- )and Cl- were found to have higher thermal stability.

Summary: Knowledge of frontier orbital energies, such as HOMO and LUMO, is crucial for studying stability, corrosion inhibition potential, and reactivity of compounds. Density functional theory (DFT) calculations provide an approach to estimate these energies, but it becomes computationally intensive for large-scale screening. In this article, a machine learning model based on extreme gradient boosting is developed to predict HOMO and LUMO energies, resulting in significantly reduced computational time.

Summary: A new strategy for direct access to fully substituted polycyclic imidazolium salts using alpha-enaminones and proline as the reagents is reported. This open-flask operation is a catalyst-, metal-, and Lewis acid-free green process, which does not require an ion-exchange step. It can produce good yields with minimal formation of side products, and is not limited to aryl substituents.

Summary: This study investigates the influence of the cation of imidazolium-derived ionic liquids on the low-temperature solution-based synthesis of hexagonal tungsten bronze type and bronze-type titanium oxides. The findings suggest that using ILs with longer alkyl chains can slow down the conversion of Ti(OH)OF·0.66 H2O to TiO2(B), indicating ILs can stabilize nanoparticles and thus delay the transformation into more stable compounds.

Summary: In this study, a polymeric ionic liquid with excellent adsorption capacity for tea polyphenol epigallocatechin gallate (EGCG) was synthesized and optimized using L-proline as the anion. The adsorption process was characterized using dynamics and isothermal research, revealing a quasi-second-order kinetic equation and monolayer adsorption mechanism. Thermodynamic parameter analysis indicated that the adsorption process is endothermic and spontaneous. The results of molecular docking demonstrated the interaction mechanisms between EGCG and the ionic liquid. This study provides guidance for the synthesis of polymeric ionic liquids and optimization of adsorption conditions, with potential applications in component adsorption and purification.

Summary: The aerobic oxidation of lignin model 2-phenoxyacetophenone (2-PAP) in cooperative ionic liquid mixtures (CoILs) with [C(2)C(1)im]OAc and [B(Z)C(1)im]NTf2 was investigated. The CoILs showed higher conversion and product yields compared to pure ILs, indicating the cooperative effects of the two ILs. [C(2)C(1)im]OAc promoted the catalytic cleavage of aryl-ether bonds and solvation, while [B(Z)C(1)im]NTf2 induced the formation of alkyl radicals and enhanced the product selectivity.

Summary: Oxide nanorolls and nanotubes were observed on the surface of amorphous Fe70Cr15B15 alloy during anodic oxidation in a hydrophobic ionic liquid. The formation of this novel nanostructure is dependent on the presence of a natural oxide film and the state of the electrode surface. The electrochemical behavior of the alloy in the ionic liquid is influenced by the surface state before oxidation, as demonstrated through partial etching with different concentrations of benzoic acid.

Summary: This article reviews the possibilities and future perspectives of electrochemical deposition of bimetallic compositions and alloys containing Fe, Co, Ni, Cr, W, and Mo. The synthesis of two- and three-component materials, as well as compositionally more complex alloys, is discussed. Electrodeposition from solutions containing metal ions and metalloids is a promising approach due to its speed, cost-effectiveness, and ability to control the composition of the final product. The correlation between the magnetic and catalytic properties of iron-triad metal alloys is considered, which can lead to a deeper understanding of the properties of electrodeposited alloys. The advantages and perspectives of electrochemical deposition from ionic liquids and deep eutectic solvents are also briefly discussed.

Summary: Liquid organic hydrogen carriers (LOHC) are considered as the safest and most promising candidates for hydrogen storage, meeting the requirements of sufficient weight and volume capacity, hydrogenation-dehydrogenation reversibility and low cost. This article focuses on the prospects of catalytic hydrogenation of polycyclic hydrocarbons for the production of LOHC. Electrocatalytic hydrogenation of aromatic LOHC is found to be highly advantageous, as it eliminates the use of gaseous hydrogen and is safer than conventional hydrogenation. The article also discusses approaches to enhance the efficiency of electrocatalytic hydrogenation.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
