“…The resulting catalysts from both studies demonstrated efficiency and reusability over multiple cycles. Ionic liquids have also been used for biodiesel production [67], and for producing catalysts for biomass transformation [31,68,69]. For instance, Abu Zarina et al [60] explored a series of HY zeolite immobilizing ionic liquid 1,4 methyl sulfonic acid imidazolium tetrachloroaluminate…”

Known as green inorganic products and environmentally beneficial, ionic liquids (ILs) are increasingly used in the ionothermal synthesis of zeolites and zeotype materials compared to the hydrothermal method. This safe and successful process offers new opportunities to produce several molecular sieves with different morphologies and structures for promising applications.In this review, we summarize the history of the most successful phases of zeolites and zeotype materials, with different structures such as AEL, AEI, AFI, AST, ATS, CHA, -CLO, ITW, LEV, LTA, MFI, MTN, MTT, SOD, TON, IRR, and STW, from ILs discovery until 2022. The use of the ionothermal method compared to the hydrothermal route is evaluated and reported in this paper, besides synthesis parameters affecting the final product formation, such as IL dosage, cation size and shape, water content, (P, Si, F, IL/Al) ratios, crystallization time and temperature, mineralizing agent, Me/Al ratio, the addition of a secondary template (co-SDA), the use of IL as both SDA and solvent, competition in forming the framework, and the use of eutectic mixture and deep eutectic solvent (DES). Furthermore, we collected the various applications of these materials and highlighted the advantages of the ionothermal process, offering a comprehensive understanding of this topic.

“…Generally speaking, the stronger the acidity of ILs, the better the transesterification catalytic performance becomes. For example, the Hammett acidity of three ILs follows the sequence of [Py][HSO 4 ] > [Py][NO 3 ] > [ATN][NO 3 ] ([Py] + = pyridinium, [ATN] + = 4-amino-1-h-1,2,4-triazolium) . The methyl oleate production with 10 wt % catalyst loading was conducted at 55 °C for 70 min, while the methyl oleate yield by using [Py][HSO 4 ] was 5- and 10-fold as that of [Py][NO 3 ] and [ATN][NO 3 ], respectively.…”

Ionic liquids (ILs) consisting entirely of ions exhibit many fascinating and tunable properties, making them promising functional materials for a large number of energy-related applications. For example, ILs have been employed as electrolytes for electrochemical energy storage and conversion, as heat transfer fluids and phase-change materials for thermal energy transfer and storage, as solvents and/or catalysts for CO2 capture, CO2 conversion, biomass treatment and biofuel extraction, and as high-energy propellants for aerospace applications. This paper provides an extensive overview on the various energy applications of ILs and offers some thinking and viewpoints on the current challenges and emerging opportunities in each area. The basic fundamentals (structures and properties) of ILs are first introduced. Then, motivations and successful applications of ILs in the energy field are concisely outlined. Later, a detailed review of recent representative works in each area is provided. For each application, the role of ILs and their associated benefits are elaborated. Research trends and insights into the selection of ILs to achieve improved performance are analyzed as well. Challenges and future opportunities are pointed out before the paper is concluded.

“…On the other hand, due to their lower vapor pressure, high thermal stability, non-flammability and high ionic conductivity, ionic liquids (IL) have been applied in various fields. 28,29 Poly(ionic liquids) (PILs) are obtained by polymerizing the IL monomer. 30 PILs combine the common features of polymeric materials with the unique properties of ILs.…”
