Synthesis of La2Ce2O7 nanoparticles by co-precipitation method and its characterization

Area of Science:

• Materials Science
• Nanotechnology
• Inorganic Chemistry

Background:

• Lanthanum cerium oxide (La2Ce2O7) is a promising material with diverse applications.
• Nanoparticle synthesis requires controlled methods to achieve desired properties.

Purpose of the Study:

• To synthesize lanthanum cerium oxide nanoparticles via a co-precipitation method.
• To characterize the synthesized nanoparticles for phase structure, morphology, and composition.

Main Methods:

• Co-precipitation followed by high-temperature calcination.
• Characterization using Thermo gravimetric analysis (TGA), X-ray diffraction (XRD), Electron dispersive spectroscopy (EDS), Transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR).

Main Results:

• TGA indicated ~37% weight loss due to water and nitrate.
• XRD confirmed the formation of cubic fluorite phase La2Ce2O7 at 600 °C.
• TEM revealed cubic nanoparticles with diameters ranging from 55 to 80 nm.
• EDS confirmed the presence of both Lanthanum (La) and Cerium (Ce).
• FTIR analysis showed residual nitrate and water absorption.

Conclusions:

• The co-precipitation method successfully produced La2Ce2O7 nanoparticles.
• The synthesized nanoparticles possess a cubic fluorite structure and nano-dimensions.
• Further studies can explore the application potential of these characterized nanoparticles.
