The intriguing properties like large surface area, tunable pore size, thermal and chemical stability have garnered significant interest to combine MetalOrganic Frameworks (MOFs) with ionic liquids (ILs) to create IL@ZIF-MOF composites. These composites have been well reported to excel in applications such as CO2 capture, catalysis, and as hybrid solid electrolytes due to their enhanced ionic conductivity. This integration leverages the benefits of both materials, enhancing catalytic stability and selectivity while providing environmental benefits. Recent advancements have not only demonstrated breakthroughs in the synthesis of IL@ZIF-MOF composites but have also highlighted their potential gap in addressing the challenges of biomass valorization, specifically, a potential to improve the efficiency and yield of biochemical production from lignocellulosic biomass—a critical source of renewable chemicals.
