Solvents Regulation and Thermodynamic Control the Morphologies of Cu₂O Nanocrystals

Abstract

Various morphologies of Cu₂O nanoparticles have been prepared in a facile method. The XRD, EDX and XPS have been adopted to verify the components of the deposits. The following parameters have been adjusted to investigate the mechanism of crystal growth: content of copper(II) acetate, reaction temperature, rate of octadecenoic acid/ethanol/water. Experiment data revealed that the nanostructures of product could be modulated through carefully control these parameters, which is expecting to be used for producing well ordered Cu₂O nanocrystals in large scale.
