The resultant nanocomposite exhibited similar high comprehensive catalytic performances as the one prepared by the regular divided-multistep method. The encapsulation of CS chains and doping of Co in the Al pillaring also contributed to the improved catalytic performance.

Summary: In this study, the catalytic properties of pillared clay for olefin removal from aromatic compounds were improved by modifying the clay porosity with organic polymer molecules. The surface area of acid-activated clay treated with calcium ion (Al-PAAC) was increased from 0.278 to 0.321 and 0.416 cm3.g-1 at PVA concentrations of 30% and 50%, respectively. The PVA-modified samples showed higher catalytic activity compared to other samples due to more active sites. The olefin conversion of the pillared sample remained above 50% in the presence of 50% PVA for more than 26 hours.

Summary: This study demonstrates the non-Faradaic electrochemical promotion of a Bronsted acid-catalyzed reaction over a metal oxide surface. The promotion is believed to originate from the generation of Bronsted acid sites localized to the three-phase boundary at the catalyst/gas/electrolyte interface and/or acid site strengthening due to electrical polarization. The effect is reversible and does not appear to permanently alter the chemistry of the Mo film.

Summary: The emission of semi-volatile heavy metals during fuel utilization poses a significant threat to the environment. This study investigated the sorption performance of montmorillonite modified by thermal treatment and hydrochloric acid activation for PbCl2. The optimal sorption temperature of the sorbents increased with thermal treatment temperature (<500 C) due to the removal of water and hydroxyl groups, but higher treatment temperatures led to the collapse of lamellar structure and hindered PbCl2 adsorption. Additionally, hydrochloric acid activation helped inhibit sorbent melting and enhanced PbCl2 adsorption at higher temperatures.

Summary: Metal borides, such as nickel borides (NixB), are widely used materials in industry. However, their exploration at the nanoscale has been limited due to synthesis difficulties. In this study, a solid-state method was developed to synthesize NixB nanopowders and convert them into colloidal suspensions. The synthesis was achieved using commercially available salts and adjusting the synthetic parameters under mild and solvent-free conditions. Through mechanistic studies, it was found that Ni nanoclusters are intermediates in the boriding process, and size control can be achieved through reaction mediators. The stabilized NixB nanocrystals were then converted into stable inks for further solution processing applications, providing tools for the development of NixB-based catalysts and other metal boride colloidal nanostructures.

Summary: In the field of biocatalysis, the implementation of sustainable processes such as enzyme immobilization or the use of environmentally friendly solvents is highly important. This study focused on the extraction of tyrosinase from fresh mushrooms and its carrier-free immobilization to create non-magnetic and magnetic cross-linked enzyme aggregates (CLEAs). The results showed that the nature and concentration of Deep Eutectic Solvents (DESs) significantly affected the catalytic activity and stability of tyrosinase, with immobilization increasing the enzyme's activity up to 3.6-fold. The biocatalyst also demonstrated great potential in modifying chitosan with caffeic acid, enhancing the films' antioxidant activity.

Summary: Nanostructured hybrids of graphene oxide and palladium were synthesized through one-step solvent-free gas phase treatment, followed by in situ decoration with palladium in the liquid medium. The proposed method offers an eco-friendly alternative for obtaining nanohybrids of graphene oxide and palladium nanoparticles under mild conditions. The hybrids demonstrated the formation of nanometer-sized crystalline palladium particles, with larger particle sizes observed for diamine-functionalized substrates compared to monoamine or non-functionalized substrates. The thermal stability of the obtained hybrids was slightly lower than pristine graphene oxide.

Summary: We propose a facile approach to prepare graphene oxide (GO) composites with lanthanide (Ln) oxide/hydroxide nanoparticles (Ln = La, Eu, Gd, Tb) under mild conditions. The mechanism of GO-Ln nanocomposite formation involves the coordination of Ln3+ ions to oxygen-containing groups of GO, followed by nanoparticle growth. The obtained nanocomposites show the honeycomb-like structure of graphene and the interaction between GO and Ln ions is confirmed. The size and distribution of Ln oxide/hydroxide nanoparticles on GO sheets vary for different lanthanides, with La-containing composites exhibiting the most homogeneous distribution. All GO-Ln nanocomposites are thermally less stable compared to pristine GO.

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.
