Paramagnetic ionic liquids for advanced applications: A review

Abstract Magnetic ionic liquids (MILs) incorporated with inorganic or organic paramagnetic ions are a new type of ionic materials having high ionic conductivity, magnetic responsiveness and sometimes integrated with luminescence activity. This material has gained considerable research attention in the past few decades due to its many amazing properties. The MILs overcome many disadvantages faced by traditional magnetic fluids. In this review, we have outlined the important properties, scopes and attributes of this novel class of ionic liquids in various fields such as catalysis, nanomaterial synthesis, extraction process, cellulose dissolution, magnetic separation, gas adsorption, density measurements and environmental remediation.
