“…Cao et al also reported the importance of using ionic liquids in combination with microwave heating to produce ZnO nanosheets, suggesting that this combination of method and solvent plays a critical role in formation of these structures. 182 Wang and Zhu showed that both ionic liquid and reaction temperature were important in controlling the morphology of Co 3 O 4 nanorods. 186 It is unclear why this combination is so effective, but its speed, the use of benign reactants, the ability to scale up product quantities, and the ultimate purity of the final product make this technique a potentially useful green application.…”

“…[240,241] Although the synthesis of metal oxides in ionic liquids or mixed solutions containing ionic liquids has just begun, the number of publications in this direction is much more than that on the synthesis of silicas using ionic liquids because of the diversity of metal oxides. Typical examples include the synthesis of TiO 2 , [47,48,[242][243][244][245][246][247][248][249][250][251][252][253][254][255] ZnO, [43,[256][257][258][259][260][261][262][263][264][265][266] CuO, [267][268][269][270][271] Cu 2 O, [272] Fe 2 O 3 , [273,274] NiO, [275] ZrO 2 , [276] Co 3 O 4 , [277,278] CeO 2 , [279,280] SnO 2 , [281,282] PbO, …”

Preparation of Inorganic Materials Using Ionic Liquids

Conventional synthesis of inorganic materials relies heavily on water and organic solvents. Alternatively, the synthesis of inorganic materials using, or in the presence of, ionic liquids represents a burgeoning direction in materials chemistry. Use of ionic liquids in solvent extraction and organic catalysis has been extensively studied, but their use in inorganic synthesis has just begun. Ionic liquids are a family of non-conventional molten salts that can act as templates and precursors to inorganic materials, as well as solvents. They offer many advantages, such as negligible vapor pressures, wide liquidus ranges, good thermal stability, tunable solubility for both organic and inorganic molecules, and much synthetic flexibility. In this Review, the use of ionic liquids in the preparation of several categories of inorganic and hybrid materials (i.e., metal structures, non-metal elements, silicas, organosilicas, metal oxides, metal chalcogenides, metal salts, open-framework structures, ionic liquid-functionalized materials, and supported ionic liquids) is summarized. The status quo of the research field is assessed, and some future perspectives are furnished.

“…Nanorods and nanowires were made out of Co 3 O 4 , 55 Te, 184 and metal sulfides 165 using RTILs and microwave heating, whereas ZnO formed flower-like nanosheets. 182 Other solvents were employed in an attempt to produce Te nanorods and nanowires. Of the solvents tested, ILs were the most successful for formation of Te nanorods and nanowires.…”
