Abstract

Lanthanum oxides have attained significant interest for their diverse applications in hydrogen storage, electrodes, sorbent
materials, gate insulators, and superconductors because of their multifunctional properties. In this present work, lanthanum
oxide was successfully synthesized through the facile microwave-assisted chemical coprecipitation method and followed by
calcination at 700°C. The crystal structure of the synthesized material was confirmed through X-ray diffraction (XRD), and
average crystallite size was calculated from the XRD data based on the Debye–Scherrer equation. Fourier transform infrared
spectroscopy (FT-IR) analysis confirms the presence of functional groups. XPS analysis was performed to examine the chemical
composition. The surface morphology has been investigated using a field emission scanning electron microscopy (FE-SEM)
technique.
