Natural deep eutectic solvents (NDESs), as a new type of green solvent, are used in many fields, including industry in extraction processes, medicine, pharmaceuticals, metallurgy, electrodeposition, separations, gas capture, biocatalysis and nanotechnology. Mainly due to their properties, such as simple preparation, environmental friendliness, biocompatibility and multifunctionality, they are being used in various fields of industry. This review aims to provide insight into the applications of natural deep eutectic solvents, specifically in nanotechnology processes. It focuses on the description of NDES and how their physicochemical properties are used to obtain functional nanomaterials, including metals, metal oxides and salts. It highlights how the use of NDESs to obtain a wide range of inorganic nanoparticles enables the elimination of disadvantages of traditional methods of obtaining them, including reducing energy consumption and functionalising nanoparticles in situ. In conclusion, recent advances and future directions in the development and applications of NDESs in nanotechnology are discussed with the aim of identifying unexplained scientific questions that can be investigated in the future.

“…Abundant hydrogen bond donors/receptors can provide efficient pathways for proton transport, reducing energy losses during the proton transfer process in batteries and leading to improved efficiency of the battery. [64][65] Chaabene et al tested the decomposition voltage and ionic conductivity of a series of electrolytes with ionic liquids as solvents and found that the electrolyte composed of 2 M acetic acid (Ac.A) added to 1-ethyl-3-methylimidazolium acetate([EMIM][Ac] + Ac.A (2 M)) showed a wide operating voltage window and high ionic conductivity (Figure 7d-e). The specific discharge capacity of AB5-alloy working electrode in different electrolytes is shown in Figure 7f.…”

Simultaneously achieving high energy density and high‐power density in energy storage systems is a crucial direction for developing next‐generation energy storage technologies. The high capacity and rapid kinetic performance of rechargeable proton batteries provide an ideal solution for overcoming energy limitation of capacitors and power constraints of traditional metal‐ion batteries. Research efforts primarily concentrated on electrode materials design, understanding the charge storage mechanisms, and exploring the failure mechanisms. While there has been relatively less emphasis on the modifications to electrolytes and electrode‐electrolyte interfaces to enhance overall performance. Summarizing and sorting relevant work is crucial in providing direction and suggestions for future research endeavors. Herein, to improve energy density, power density, and cycle stability of proton batteries, a series of recently published studies on electrolyte and electrode‐electrolyte interfaces are discussed and reviewed. Furthermore, challenges and future directions pertaining to the electrolytes of proton batteries have been identified, offering insights to facilitate the development of proton battery technology.

Ionic liquids (ILs), as one of the most concerned functional materials in recent decades, have opened up active perspectives for electrocatalysis. In catalyst preparation, ILs act as characteristic active components besides media and templates. Compared with catalysts obtained using ordinary reagents, IL-derived catalysts have a special structure and catalytic performance due to the influence of IL’s special physicochemical properties and structures. This review mainly describes the use of ILs as modifiers and reaction reagents to prepare electrocatalysts for water splitting. The designability of ILs provides opportunities for the ingenious composition of cations or anions. ILs containing heteroatoms (N, O, S, P, etc.) and transition metal anion (FeCl4−, NiCl3−, etc.) can be used to directly prepare metal phosphides, sulfides, carbides and nitrides, and so forth. The special physicochemical properties and supramolecular structures of ILs can provide growth conditions for catalysts that are different from the normal media environment, inducing special structure and high performance. ILs as heteroatom sources are safe, green and easy to operate compared with traditional heteroatom sources. The strategy for using ILs as reagents is expected to realize 100% atomic transformation of reactants, in line with the concept of green chemistry. This review reflects the discovered work with the best findings from the literature. It will offer readers a deeper understanding on the development of IL-derived electrocatalysts and inspire them to ingeniously design high-performance electrocatalysts for water splitting.
