Background:

• Controlling the morphology of metal oxide nanostructures is crucial for tailoring their properties.
• Copper oxide (CuO) nanostructures have diverse applications, necessitating controlled synthesis methods.

Purpose of the Study:

• To investigate the influence of different additive molecules on the morphology of copper oxide (CuO) nanostructures.
• To synthesize flower-shaped and ellipsoidal-shaped CuO structures using a facile solution method.
• To characterize the structural properties of the synthesized CuO nanostructures.

Main Methods:

• A simple, low-cost solution method was employed for CuO synthesis.
• Two distinct additive molecules, hexamethylenetetramine and triethylamine, were used to direct morphology.
• Morphological and structural characterizations were performed on the synthesized products.

Main Results:

• Two distinct CuO morphologies, flower-shaped and ellipsoidal-shaped, were successfully synthesized.
• The study confirmed a strong dependence of CuO morphology on the specific additive molecule used.
• Structural characterization revealed the nanocrystalline nature and monoclinic structure of both CuO morphologies.

Conclusions:

• Specific additive molecules can be effectively utilized to control and obtain desired CuO nanostructure morphologies.
• The facile solution method provides a cost-effective route to synthesize tailored CuO nanostructures.
• The synthesized flower-shaped and ellipsoidal-shaped CuO structures possess nanocrystalline monoclinic characteristics.
