Synthesis and characterization of CuO nanowires by a simple wet chemical method

Abstract

We report a successful synthesis of copper oxide nanowires with an average diameter of 90 nm and lengths of several micrometers by using a simple and inexpensive wet chemical method. The CuO nanowires prepared via this method are advantageous for industrial applications which require mass production and low thermal budget technique. It is found that the concentration and the quantity of precursors are the critical factors for obtaining the desired one-dimensional morphology. Field emission scanning electron microscopy images indicate the influence of thioglycerol on the dispersity of the prepared CuO nanowires possibly due to the stabilization effect of the surface caused by the organic molecule thioglycerol. The Fourier transform infrared spectrum analysis, energy dispersive X-ray analysis, X-ray diffraction analysis, and X-ray photoemission spectrum analysis confirm clearly the formation of a pure phase high-quality CuO with monoclinic crystal structure.

Investigation of sol-gel processed CuO/SiO2 nanocomposite as a potential photoanode material

“…These peaks are consistent with the JCPDS data Card No. 48-1548 of the CuO with a monoclinic phase [21] identical to that of pure CuO [22]. The lattice parameters corresponding to the above data card were found to be a = 4.688Å, b = 3.422Å and c = 5.131Å, respectively [23].…”

CuO Nanoparticles Supported on TiO2 with High Efficiency for CO2 Electrochemical Reduction to Ethanol

“…Moreover, additional confirmation of CuO state was seen with the broad satellite peaks at a higher binding energy than the main peaks. The main peak of Cu 2p 3/2 at 933.8 eV was accompanied by two satellite peaks on the higher binding energy side at about 943.8 eV and 941.5 eV, which suggests the existence of CuO [38][39][40][41]. From this figure, we can clearly see that the main peak of Cu 2p 1/2 at 953.8 eV and its satellite peak at 962.5 eV were separated by about 9.0 eV, which also confirms the presence of CuO [42].…”

Tuning the magnetic properties of high aligned strontium ferrite nanowires formed in alumina template

“…Uniformly distributed nanowires can have a key role in development of magnetic evaluation of ferromagnetic and ferrimagnetic. Although various magnetic metal or metal oxides have been fabricated and characterized [9,16], limited information is available regarding the hexaferrites with one dimensional structure. Strontium ferrite is the kind of hexaferrite with magnetoplumbite structure; energy density of magneto-crystalline anisotropy constant (3.7 Â 10 6 erg/cm 3 ) is comparable to that of shape anisotropy (2.5 Â 10 3 erg/cm 3 ).…”
