Convenient green production of CeO2 nanoparticles by the auto combustion method

Abstract

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.
