A spray drying system for synthesis of rare-earth doped cerium oxide nanoparticles
We have constructed a spray-dryer to synthesize doped ceria nanoparticles. This system was employed to synthesize mixed oxide nanoparticles of praseodymium doped (3%, 10% and 20mol %) ceria. X-ray Diffraction (XRD) confirmed the fluorite-like cubic crystal structure of the synthesized materials after calcination. As-dried CeO2 samples were found to have an average particle size of 6nm which after calcination at 700 C for 2hrs increased to 17nm with an improvement in crystallinity. The particle size increased for 3% and 10% Pr doped samples but nearly doubled for the 20% case. The lattice parameter of ceria was found to obey Vegard s law.
