Synthesis and Catalytic Activity of Highly Dispersed Solid Solutions Ce0.9Sn0.1O2 and Ce0.8Sn0.1Zr0.1O2 in CO Oxidation
Fluorite-like solid solutions of Ce 0.9 Sn 0.1 O 2 and Ce 0.8 Sn 0.1 Zr 0.1 O 2 were synthesized by coprecipitation using ammonium carbonate as a precipitant. The samples were characterized by X-ray powder diffraction analysis, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy...

The samples were characterized by X-ray powder diffraction analysis, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy, low-temperature nitrogen adsorption, and gas chromatography. It was shown that the solid solutions are formed already at an annealing temperature of 550°C. In this process, platelike particles are formed, the size of which, according to SEM data, is 4 μm. The synthesized materials have a mesoporous structure. The specific surface areas of Ce
