CuCl Nanoplatelets from an Ionic Liquid‐Crystal Precursor

Abstract

Research on ionic liquids (ILs) has focused on the synthesis of and organic chemistry in ILs. Recently, however, ILs have also received attention from the inorganic materials community. Ionic liquids can act as solvents for reactants and morphology templates for the products at the same time, which enables the synthesis of inorganic materials with novel or improved properties. In principle, the IL can be retrieved after synthesis and thus provides an ecologically friendly and economical approach to inorganic materials. While ILs are promising "all-in-one" solvent/templates for the synthesis of inorganic materials, only a few reports on this topic have appeared; they have mainly focused on ordered metal oxides [1][2][3][4][5] and metal nanoparticles. [6][7][8] For a recent review on the structural organization in ionic liquids, see also ref. [9] Copper(i) chloride is extensively used as a desulfurizing agent in the petrochemical industry and as a catalyst for the denitration of cellulose; [10] there is thus considerable interest in improved CuCl systems. This paper introduces a novel

Photoreduction of a crystalline Au(III) complex: A solidstate approach to metallic nanostructures

“…The exothermic peak observed here, however, is similar to DSC traces of mixtures of dodecylpyridinium tetrachlorocuprate and 6-O-palmitoyl ascorbic acid, where the exothermic peak is due to the reduction of Cu(II) to Cu(I) and the formation of CuCl crystals. 12,13 Here, the exothermic DSC peak is due to the thermal reduction of Au(III) to Au(0).…”

“…As these ILCs serve as precursors for inorganic matter, we have termed them ionic liquid crystal precursors, ILCPs. 12,13 Unlike conventional precursor/solvent/ reactant mixtures, ILCPs are "all-in-one" reactant-solventtemplates. 3,12,13 Other research groups have recently adapted this concept and presented their own ILCPs.…”

Supramolecular Structures in the Presence of Ionic Liquids

“…The ionic conductivities and LC structures of the obtained 1-methylimidazolium ILs could be conveniently adjusted by anions, which would potentially be used as an on-off switch of ions ( Figure 17) (Yazaki et al, 2008b). Besides imidazolium ionic LCs, other thermotropic ionic LCs based on pyridinium (Bowlas et al, 1996;Cruz et al, 2000;Cui et al, 2002;Gordon et al, 1998;Neve et al, 2000;Neve et al, 2001;Taubert, 2004), quaternary ammonium (Alami et al, 1993;Arkas et al, 1999;Lu et al, 1997;Pott & Meleard, 2009;Tittarelli et al, 1997), quaternary phosphonium (Abdallah et al, 2000;Chen et al, 2002;Gowda et al, 2004), pyrrolidinium (Goossens et al, 2009), dithiolium (Artzner et al, 1997) and guanidinium ILs (Kim et al, 2005;Mathevet et al, 2005;Sauer et al, 2008) have also been explored. Two important phenomena should be especially noticed.…”

The ionic liquid [Bmim][FeCl₄] catalyzes the formation of iron doped mesoporous silica aerogels for H₂O₂ decomposition

“…Among others, inorganic nano-and microparticles such as CuCl [6], Ag [7], or Au [7] have been made by using ILs as precursors, where the IL provides at least one component of the final material. Accordingly, these ILs have been termed ionic liquid precursors (ILPs) [8] and an analogous synthesis strategy has also been developed for (doped) carbon materials [9] [10] [11], Ni and NiO nanomaterials [12], CuS [13], Fe 3 C [14], In 2 O 3 [15], ZnO [16], CuO [17]. Other studies have focused on the synthesis using fluorine-containing anions as fluoride precursors [18] [19] [20].…”
