Summary: To produce green hydrogen, the development of high-performance, environmentally friendly, and cost-effective electrocatalysts for efficient hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is essential. This study explores the potential application of water-containing deep eutectic solvents (DESs) in the synthesis of nanostructured electrocatalysts for water electrolysis. The CU10W electrode, prepared by electrodeposition in a water-containing choline chloride/urea DES, exhibits excellent bifunctional activity toward HER and OER, with reduced overpotentials and improved stability.

Summary: This paper introduces the advantages of nanocellulose derived from lignocellulose materials, such as high strength, lightweight, biodegradability, and renewability. Due to the complex and dense cell wall structure and poor solubility in water and most solvents, lignocellulose materials are difficult to dissolve directly and utilize effectively in practical production. The pretreatment technology is discussed, which exposes the amorphous areas, eliminates unnecessary non-cellulose components, and facilitates the subsequent applications. Traditional and green solvents used in the pretreatment of lignocellulose materials, as well as their mechanisms, advantages, and disadvantages, are introduced. Furthermore, the mechanism, process, advantages, and potential applications of deep eutectic solvent as a pretreatment solvent are discussed, along with suggestions for the future use of green solvents in treating lignocellulose materials.

Summary: In this study, switchable ionic liquids were synthesized and screened to improve the polarity and recyclability of deep eutectic solvents. By coupling with hydrogen-bond donors, a switchable-DES system with modified properties, such as viscosity, conductivity, and pH, was formed, leading to enhanced solubility of lignin compounds and improved molecular weight and uniformity. This proposed system has potential applications in the fractionation of lignin compounds and downstream industrial processes.

Summary: In this study, the anionic homopolymerization, random and block copolymerizations of several vinyl monomers were explored in deep eutectic solvent (DES). The microstructures and molecular weights of the polymers were characterized, and their thermal properties were investigated. The results showed that DES can be used to prepare polymerization products with desired characteristics, and it can be recycled for multiple reactions without affecting the final product. The use of DES as a reaction medium for anionic polymerization offers milder reaction conditions and expands the application of active organolithium reagents.

Summary: A green approach was used to synthesize heterostructures of g-C3N4@MoO3 and their structural, morphological, and optical features were characterized by XRD, UV-vis, SEM, and FTIR techniques. The XRD analysis showed higher crystallinity and intensity of g-C3N4/MoO3 compared to g-C3N4 and MoO3. The g-C3N4 exhibited a crumpled layered arrangement while MoO3 had a rod-like structure. The optical properties of g-C3N4/MoO3, including refractive index, bandgap energy, and extinction coefficient, were significantly enhanced.
