Abstract

Supercritical carbon dioxide (scCO₂) has gained prominence in green chemistry due to its eco-friendly nature and unique properties, including low viscosity, nearly zero surface tension, and tunable characteristics. However, its nonpolar nature limits applications to nonpolar systems. The development of scCO₂ microemulsions with polar cores, especially those incorporating ionic liquids, addresses this limitation and expands its use across diverse fields such as cleaning, personal care, food, pharmaceuticals, materials science, and oil and gas recovery, while reducing environmental impact. Despite progress, challenges remain in understanding the thermodynamic phase behavior, nanostructure formation, and molecular dynamics of these systems. Additionally, their potential in catalysis, metal-organic frameworks (MOFs) synthesis, and polymer foaming is underexplored. This review systematically examines advancements in scCO₂ microemulsions, bridging fundamental research with applications, and highlights their promise for driving innovation in sustainable industrial processes and advancing green chemical solutions.

期刊介绍： The Journal of Supercritical Fluids is an international journal devoted to the fundamental and applied aspects of supercritical fluids and processes. Its aim is to provide a focused platform for academic and industrial researchers to report their findings and to have ready access to the advances in this rapidly growing field. Its coverage is multidisciplinary and includes both basic and applied topics. Thermodynamics and phase equilibria, reaction kinetics and rate processes, thermal and transport properties, and all topics related to processing such as separations (extraction, fractionation, purification, chromatography) nucleation and impregnation are within the scope. Accounts of specific engineering applications such as those encountered in food, fuel, natural products, minerals, pharmaceuticals and polymer industries are included. Topics related to high pressure equipment design, analytical techniques, sensors, and process control methodologies are also within the scope of the journal.
