Sažetak
Pure and manganese doped ceria samples were prepared via hydrothermal synthesis. After thermal treatment at 500°C for 2 hours, samples were characterised by transmission electron microscopy (TEM), X-ray diffraction (XRD) and N2 adsorption-desorption isotherms. XRD shows only the presence of fine ceria particles (ICDD 34- 0394). Crystallite size calculated by the Scherrer equation shows that manganese doping stabilizes nano ceria in the course of thermal treatment. Surface properties also benefit from manganese doping gaining greater specific surface area (SSA) and pore size values. While the volumes of the samples used in each of this analysis differ and methods are based on various models, nanoparticle sizes show reasonable concordance with all three methods used.
