Summary: In this study, two stable Fe(II) coordination compounds were synthesized and showed different catalytic activities when used for the Friedel-Crafts reaction. Compound 2 exhibited superior catalytic activity compared to 1 due to the coordination sites in Fe(II) facilitating intermediate formation and enhancing the electrophilic nature of beta-nitroalkenes. The high functional group and solvent tolerance of catalyst 2 allows for at least 3 times of recycling and reuse without significant loss of catalytic activity. This work presents a new strategy for the synthesis of indole alkaloids under ambient conditions.

Summary: The dual-site synergistic effect in heterogeneous catalysis is intriguing but complex. It involves two spatially separated and functionally independent active sites for the adsorption and activation of at least two substrate molecules. This complexity becomes more challenging when the substrate molecules are large. In this study, the replacement of Al3+ with Co2+ in Al4B6O15 lattice creates unsaturated Co2+ (4-fold coordination) and oxygen vacancies (O-v). These dual sites, acting as Lewis acid and oxygen adsorption sites, synergistically catalyze the Friedel-Crafts alkylation reactions of nitro-substituted molecules and indole derivatives. The catalyst exhibits high durability and the addition of hydrogen further enhances its catalytic activity, providing a novel perspective on the development of dual-site catalysts.

Summary: Among cross coupling reactions, C-C cross coupling reaction has attracted much attention and progress in the past four decades. Pd, one of the transition metals, has shown the highest activity due to its unique features and reactivity. However, due to the high cost and self-deactivation of Pd-based homogeneous catalysts, researchers have turned their focus towards the development of Pd-based heterogeneous catalysts. Metal organic frameworks (MOFs) have been frequently used as host matrix for the deposition of Pd(II) salts and Pd nanoparticles. This review provides a design and development of Pd-based MOFs as heterogeneous catalysts for C-C cross coupling reactions.

Summary: Light can enhance ozone efficiency in advanced oxidation processes (AOPs) through direct ozone photolysis or by using a photocatalyst that can be excited by UV-Vis or solar light. This review summarizes literature data on the combination of ozone and the g-C3N4 photocatalyst for water treatment. The combination shows higher efficiency than the individual treatments, attributed to the synergy between g-C3N4's efficient electron quenching by O-3 and the generation of hydroxyl radicals.

Summary: Ni nanoparticles (approximate to 8 nm) strongly grafted on N-doped graphitic carbon matrix, supported by chitosan, were used as catalyst for H2 storage/release on N-ethylcarbazole (EC). The addition of minute amounts (18 ppm) of Pt significantly increased the H2 storage/release activity of Ni@(N)C due to effect of Pt promoting H spill over the Ni NPs. After four cycles, (Pt)Ni@(N)C exhibited some fatigue in the H2 storage/release of the same EC batch, but no changes were observed in the XRD, TEM and XPS characterization of the catalyst.

Summary: In this study, a series of novel MOF-on-MOF composites were prepared and their photocatalytic activity in overall water splitting under simulated sunlight irradiation was examined. Among these composites, UiO-66(Zr)-NH2@UiO-66(Ce) exhibited promising photocatalytic activity. The enhanced activity of UiO-66(Zr)-NH2@UiO-66(Ce) was attributed to its appropriate energy band diagram and ability for photoinduced charge separation, as revealed by various spectroscopic measurements.

Summary: Graphene, a two-dimensional material with a large surface area, is widely used in various fields. Recently, there has been increased focus on developing metal-free graphenes doped with heteroatoms as efficient electrocatalysts for oxygen reduction reactions (ORRs). Our study found that graphene prepared from graphene oxide (GO) by pyrolysis under a nitrogen atmosphere at 900 degrees C showed better ORR activity compared to pristine GO. Various pyrolysis conditions were tested, and the results suggest that the ORR electrocatalytic activity of graphene is influenced by these conditions. The prepared graphenes, particularly G100-1B and G100-2B, displayed promising ORR activity for fuel cell and metal-air battery applications.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
