Syntheses of CuO nanostructures in ionic liquids

Abstract: A simple and efficient approach is developed to fabricate single-crystalline CuO nanostructures through an ionic liquid assisted one-step low-temperature solid-state route. Both nanoparticles (5 nm in size) and nanorods (5-10 nm in diameter and 50-100 nm in length) of monoclinic CuO were obtained. These synthesized CuO nanostructures were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED), X-ray photoelectron spectroscopy (XPS), energy di… Show more

“…It was proposed that the imidazolium cation interacts through the acidic 2-H proton rather than through the p system of the imidazolium core, with certain growth facets leading to the rodlike growth of ZnO. [67] For [C 8 mim][Tf 2 N] (sample 2) and [C 10 mim][Tf 2 N] (sample 3), which contain an acidic 2-H proton, nanorods were not obtained, rather spherical particles. Notably, on using an IL in which the acidic position was blocked by an alkyl group, such as in [EDimim][Tf 2 N] (sample 4), rod-shaped ZnO, with a diameter of 20 nm and a length of 50-200 nm, was still obtained.…”

“…Recently, ionic liquids, a new class of solvents with ionic character, have been widely employed in organic reactions and electrochemical devices, because of their negligible vapor pressure, high ionic conductivity, and a large electrochemical window. However, in contrast to successful applications in organic and electrochemistry, the use of ionic liquids in inorganic synthesis is still in its infancy. Most recently, the advantages of ionic liquids in inorganic synthesis have been gradually realized; a few inorganic materials, such as mesoporous silica and supermicroporous silica, iridium and gold nanoparticles, TiO 2 nanocrystals and microspheres, Te and CoPt nanorods, and so on, have been fabricated in ionic liquids. However, to our best of knowledge, systematic investigations on the relationship between the structures of ionic liquids and the morphology of ZnO nanostructures have no report hitherto.…”

“…Cubic NPs with a size of ∼100 nm can be synthesized by microwave irradiation, 15) and large aggregates composed of NPs ∼50 nm in size can be obtained by the decomposition of copper complexes. 16,17) However, the use of RTILs for controlling the nanostructure (such as core-shell and hollow structures) of Cu 2 O NPs has not been extensively investigated. Recently, we reported the preparation of various metal NPs by sputter depositing metals in RTILs under reduced pressure (RTIL/metal sputtering).…”
