“…3. The XRD patterns matched with nickel oxalate dihydrate NiC 2 O 4 ·2H 2 O (JCPDS card 14-0742), similar patterns were obtained by Malecka et al [9], and recently by Luo et al [22]. The product crystallinity was relatively superior for particles synthesized in ELM systems containing 10% extractant when compared with 1% extractant, implying that greater availability of nickel at the reaction site within the emulsion globules result in superior growth of nickel oxalate crystals.…”

“…[324] More recently, Luo et al prepared copper, nickel, manganese, cobalt, and zinc oxalates in [BMim][Cl] via conventional one-step solid-state reactions at room temperature. [325] These studies have furnished interesting examples of the synthesis of metal oxalates in the presence of 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.

“…About 30 min later, 5 mL H 2 O 2 was dropped in the mixture very slowly. After that, the mixed solution was maintained stirring at room temperature for 3 h. The brown precipitate was separated by centrifugation, washed several times with distilled water, and absolute ethanol to remove impurities and recollect the IL [17][18][19]. Finally, the brown product was dried in an oven at 70°C for 12 h.…”

Mn 3 O 4 nanoparticles were synthesized via an ionic liquid (IL) assisted process at room temperature, which is rather difficult to achieve by other techniques. The synthesized product was characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) spectroscopy, thermal gravimetry (TG), and vibrating sample magnetometry (VSM). The prepared material showed a high purity, while crystallite size and particle size agree well with each other, 17 ± 2 and 19 ± 3 nm, respectively, revealing nearly single crystalline character of nanoparticles. The product contains 4 wt% of adsorbed water and ionic liquid. This method provides a facile, one-step, and low-cost route for the synthesis of nanostructures of metal oxides. In addition, [BMIM]BF 4 could be collected and reused for subsequent reactions.
