The production of cerium oxide (CeO₂) nanoparticles was investigated using an innovative and straightforward combustion method. In this approach, cerium oxide nanoparticles were generated from the precursor Ce(NO₃)₃·6H₂O through a combustion technique that utilized varying concentrations of jojoba oil as a fuel agent. The synthesized nanoparticles were characterized through X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). The XRD analysis indicated that the cerium oxide nanoparticles had a cubic structure, with an average particle size of approximately 38.97 nm when using 3 mL of oil and 75.56 nm with 5 mL of oil, demonstrating good crystallinity. The FT-IR spectrum clearly showed a significant presence of cerium oxide nanoparticles. Overall, the results suggest that the combustion method is an effective and cost-efficient technique for producing high-quality cerium oxide nanoparticles.
