Sem Images Of Cuo Obtained After Different Reaction Time A D 3 H B Results show that the optimization of the three parameters was obtained under the following reaction conditions: t = 500 °c, time = 2 h, [cu(no 3) 2] = 0.1 mol dm −3, and at ph 3. the appropriate mechanisms of the formation of cuo nanoparticles were proposed by the authors as follows. Thus, ftir result suggests that the formation of copper oxide compound is obtained after annealing process in this method accompanying the presence of cu o bonds corresponding to cu o stretching modes. figure 3(a d) are sem images illustrating the morphologies of cuo nanoparticles prepared with different precursors via the precipitation method. We can conclude that after 3 h, cuo microspheres are formed by the self assembly of particles, but the surface of microspheres is uneven; there are still many small particles attached to the surface of microspheres (fig. 4a, d). with the extension of reaction time, these particles gradually ripe and the final structures are formed (fig. 4c, f). With an increase in the current regime to 3 a, the structure retained the shape characteristic of cuo. figure 3d,e shows sem images of cuo particles at 3a which exhibit a petal like morphology.

Sem images of cuo nanostructures obtained via hydrothermal oxidation method after (a) 1 h, (b) 3 h, and (c) 6 h. (d) cv curves of the cuo samples after 1, 3, and 6 h of synthesis time. Abstract cuo nanosheets have been synthesized via the hydrothermal method at 120°c for 3 h, without using any surfactant or structure directing agent. the structural and morphological characteristics of the copper oxide have been examined with x ray diffraction (xrd), fourier transform infrared spectroscopy (ir), scanning electron microscopy (sem), uv visible spectroscopy, and bet surface.
