Study On the Structure, Texture and Thermal Stability of Cezryo₂ Nanoparticles Synthesized Via Microemulsion Method

The CeZrYO₂ (CZY) was synthesized via microemulsion method. Phase structure, texture, and thermal stability of CZY nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), N₂ adsorption-desorption and thermogravimetric Analysis (TGA). XRD analysis confirmed the cubic phase and homogeneous solid solution of CZY nanoparticles formed. TEM micrograph also revealed the CZY nanoparticles well-defined crystallite, spherical shaped and nano scale size in range of 5-10 nm. The surface area of CZY nanoparticles was 219.50 m²/ g and isotherm profile was meso porous type IV. It was also found that the synthesized CZY nanoparticles remain a good thermal stability, in the range of temperature more than 900 degree Celsius according to thermo gravimetric analysis. (author)
