Characterization of CuO nanorods

Copper oxide nanostructures are well described in the literature, and a wide range of information on their synthesis and properties has been available for a long time. Especially copper oxide in the form of nanowires has the highest interest.
In this work, a crystalline and molecular structure of films containing CuO nanorods obtained by PVD process and thermal oxidation are studied. In the first step, on the Cu substrate, a carbonaceous-nickel film was deposited. Such modified substrate was heating in the air at 650℃. As a result, CuO nanorods were grown. High-resolution transmission microscopy (HRTEM) was applied to study details of the structure of nanorods. The molecular structure was studied by Fourier-transform infrared spectroscopy (FTIR).
