چکیده
We exploited a solution-based route for preparation of Cu, Cu(2)O, Cu(3)N, and Cu(2)S nanocrystals, that is, direct thermal decomposition of copper salts (Cu(NO(3))(2), CuSO(4)) in octadecylamine (ODA) solvent, which is a novel and ingenious chemical process.

Shape-controllable and versatile synthesis of copper nanocrystals with amino acids as capping agents.
Thanks to their outstanding properties and a wide range of promising applications, the development of a versatile and convenient preparation method for metallic copper nanocrystals with controllable shape is of primary significance. Different from the literature that utilized a capping agent bearing only one kind of Cu binding functionality, either an amino or a carboxylic unit, for their prepa...
متن کاملColloidal synthesis of magnetic CuCr2S4 nanocrystals and nanoclusters.
Nanocrystals and nanoclusters of the room-temperature magnetic spinel CuCr(2)S(4) have been synthesized using a facile solution-based method. The synthesis involves hot injection of an excess of 1-dodecanethiol (1-DDT) into a boiling coordinating solvent containing CuCl(2) and CrCl(3)·6H(2)O. Using octadecylamine (ODA) as a solvent yields cube-shaped nanocrystals with an average size of 20 ± 2 ...
متن کاملA facile green antisolvent approach to Cu2+-doped ZnO nanocrystals with visible-light-responsive photoactivities.
An environmentally benign antisolvent method has been developed to prepare Cu(2+)-doped ZnO nanocrystals with controllable dopant concentrations. A room temperature ionic liquid, known as a deep eutectic solvent (DES), was used as the solvent to dissolve ZnO powders. Upon the introduction of the ZnO-containing DES into a bad solvent which shows no solvation to ZnO, ZnO was precipitated and grow...
متن کاملHigh-purity Cu nanocrystal synthesis by a dynamic decomposition method
Cu nanocrystals are applied extensively in several fields, particularly in the microelectron, sensor, and catalysis. The catalytic behavior of Cu nanocrystals depends mainly on the structure and particle size. In this work, formation of high-purity Cu nanocrystals is studied using a common chemical vapor deposition precursor of cupric tartrate. This process is investigated through a combined ex...
متن کاملA versatile strategy to the selective synthesis of Cu nanocrystals and the in situ conversion to CuRu nanotubes.
Compared with Ag, Au, Pt and Pd, the synthesis of Cu nanocrystals that exhibit well-defined structures and surface properties has achieved limited success. Herein, we report an etching and protecting strategy to prepare Cu nanostructures with controllable shapes, crystalline nature and surface properties. In the developed strategy, the selective use of different additives is critical to the suc...
