A Review of Ionic Liquids: From Solvent Applications to Template‐Assisted Synthesis of Metal Oxide Nanoparticles

ABSTRACT Ionic liquids (ILs) have attracted considerable scholarly attention owing to their unique properties and extensive applicability across diverse domains. The exceptional characteristics of ILs present numerous avenues for the conception and progression of various avant‐garde materials, including highly proficient catalysts. In recent years, a substantial body of research has been conducted on the synthesis and application of different categories of catalytic materials within chemical reactions. This has resulted in the topic becoming very captivating and worthy of study. This work presents a thorough examination of the process of producing catalytic materials by utilizing ILs as either the medium or functional components. Our primary focus is on thoroughly researched themes such as metal nanocatalysts/IL, functional IL/support, metals or metal oxides/IL/support, and polymeric ILs (PILs) catalysts. Moreover, we place particular emphasis on the efficiency of these catalytic systems.
