SYNTHESIS AND CHARACTERIZATION OF NITROGEN- DOPED CERIUM OXIDE NANOPARTICLES USING CO- PRECIPITATION METHOD

• Nanomaterials are being highly attracted by researchers to exploit their excellent properties for various applications. • Cerium is the most excessive among rare earth elements, occupying at about 66 parts per million of the earth crust, and also presently a subject of great care due to its multiple applications, which include materials for catalysis, gas sensors, solid oxide fuel cells, ceramics, and oxygen storage. • Numerous methods, including precipitation from solution , microwave assisted method , hydrothermal synthesis, sol-gel process , solvo thermal method have been used to prepare ceria nano particles with different morphologies. • Among them, I had used co-precipitation method for the synthesis of cerium oxide nanoparticles because the method is simple, easy scale-up and cost effective. • In this , I had synthesized cerium oxide nanoparticles using urea as capping and reducing agent, it was also known as carbamide and it is easily soluble in water. It is used as a nitrogen source for the synthesis of nanoparticles.
