In TEM images the presence of Cu is observed in the form of nanoparticles or clusters. It is noted that the copper oxide nanoparticles have predominantly spherical shapes and the most extensive dark bands are agglomerates of such particles. As confirmed by the XRD analysis (Figure 1) the largest nanoparticles exceed little more than 100 nm.
