Size-Controlled Cu₂O Nanocubes by Pulse Electrodeposition

Abstract

: In this work, highly uniform size-controlled Cu 2 O nanocubes can be successfully formed by means of pulse electrodeposition. The size distribution, crystal structure, and chemical state of deposited Cu 2 O nanocubes are characterized using scanning electron microscopy, transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. The phase transition from Cu 2 O to Cu can be controlled by constant current electrodeposition as a function of deposition time. In particular, the size of the Cu 2 O nanocubes can be controlled using pulse electrodeposition as a function of applied current density.

Potentiostatic Deposition and Characterization of Cuprous Oxide Thin Films

“…From both SEM and XRD one can explain that these spherical grains are metallic copper. Song et al have proved this explanation with XPS (X-ray Photoelectron Spectra) measurements [19].…”

“…By continuing the deposition process to 15 min, spherical grain started to appear on the surface (Figure 1(c)). Finally after 30 min deposition time, it was found that the density of the spherical grains increased to cover most of the surface as it is clear in Figure 1(d) [19].…”

Graphite Studded with Facile-Synthesized Cu2O Nanoparticle-Based Cubes as a Novel Electrochemical Sensor for Highly Sensitive Voltametric Determination of Mebeverine Hydrochloride

“…Among cuprous oxide transversal forms, cubes may be the most interesting because of their tailor-made properties and their high symmetries, other more complex structures can be obtained from these simple structural forms [6,7]. It was reported about the self-assembly of Cu2ONPs to form microspheres and microcubes [8].…”
