New materials, which are eco-friendly and have unusual characters, are so attractive with the increasing demand and harmful pollutants amount all over the world. As a solvent, non-evaporate ionic liquids (ILs) have recently captured notable interest due to their magnifical properties. They have been used for distinct purposes such as electrochemistry, separation, lubrication, catalyst, and energy applications. Adding functional groups and/or anion or cation tunability can ensure improved efficiency ILs depends on the application type. The preset paper is primarily focused on the ionic liquids (IL) synthesis, development of functionalized ionic liquids, and their purification process. It also provides a review of the use of ionic liquids as electrolytes in the thermoelectrochemical cells due to the immediate necessity in areas ranging from waste heat conversion to electricity in modern life. Because ionic liquids have hazardous environmental effects, incur high costs, and require complex synthesis and purification process, all must be under control, recovered and optimized. Therefore, understanding their nature has become more important. Additionally, viscosity and conductivity of ILs are an obstacle in experimental studies; besides, the use of redox couples in IL electrolytes must be improved to use in thermoelectrochemical cell applications.

“…Với vai trò là xúc tác cho phản ứng, chất lỏng ion có nhiều tính chất vật lý nổi bật đã được nghiên cứu như áp suất hơi bão hòa thấp, nhiệt độ nóng chảy thấp, quá trình điều chế đơn giản, độ nhớt cao, độ dẫn ion cao, độ phân cực thấp, dễ dàng thu hồi và tái sử dụng [18]. Ngoài ra, chất lỏng ion còn được ứng dụng nhiều trong lĩnh vực khác như chất điện giải trong pin, hấp thụ khí, dung môi ly trích,… [19,20].…”

[(SO3H)4C4C1Im]HSO4 is a Brönsted ionic liquid, which was found to be an effective catalyst for organic synthesis. Ionic liquid was prepared from 1-methylimidazole and 1,4- butanesultone (ratio = 1:1), structure of [(SO3H)4C4C1Im]HSO4 was characterized by using nuclear magnetic resonance NMR spectroscopy and high-resolution electrospray ionisation mass spectrometry (HR-ESI-MS). Ionic liquid was used as a catalyst for multi-component reaction, which afforded the desired products in high yields (over 80%) and short reaction time (5 min) under microwave irradiation. The catalyst could be recycled several times without loss of efficient catalytic activity.
