Fig.5. UV-spectrum of copper oxide nanoparticles stabilized by “HF”
If we pay attention to the results of the experiment, we found that the cause of
the formation of copper oxide nanoparticles in 333-353 K heat is in the presence of
dissolved oxygen in the solution. Oxygen in the solution oxidizes the emerging copper
nanoparticles, and copper oxide nanoparticles are stabilized by “HF” molecules. At a
temperature of 363 K, the oxygen content in the solution decreases. Therefore, at this
temperature, copper nanoparticles stabilized with “HF” molecules are formed in the
solution.
