Abstract

Lanthanum Oxide (La2O3) nanoparticles are successfully synthesized by simple reflux method using starting materials Lanthanum Nitrate and Urea. Lanthanum Oxide (La2O3) have multiple applications such as gas sensors, catalyst, Hydrogen storage, catalysts, photocatalytic wet oxidation etc. This paper mainly focuses on the synthesis of Lanthanum Oxide (La2O3) nanoparticles at different precursor concentration at different reaction time on the properties of the synthesized Lanthanum Oxide (La2O3) nanoparticles can be explored. The synthesized samples were calcinated 500ºC for 1hr. The Lanthanum Oxide (La2O3) nanoparticles were investigated by XRD, FTIR, SEM, & UV studies. The morphology and particle size were analyzed by SEM. The structure of the crystallites was investigated using powder XRD technique. The FTIR analysis was used to examine the functional groups present in the synthesized Lanthanum Oxide (La2O3) nanoparticles. The optical band gap was calculated from the UV-Vis absorption spectra.
