Effect of dopant elements on structure and morphology of SnO2 nanoparticles

Pure SnO2 and doped SnO2 nanoparticles with 2 wt.% ruthenium, 2 wt.% vanadium, and 2 wt.% antimony were synthesized via sol–gel and coprecipitation methods. The obtained doped and undoped dried powders after calcination treatment at different temperatures (973–1223 K) were studied. The structural and morphological characterization of the prepared samples was performed by X-ray powder diffraction (XRD), scanning electron microscope (SEM),...
