Synthesis, Antimicrobial Activity, and Photocatalytic Performance of Ce Doped SnO₂ Nanoparticles

This work represented the synthesis of Ce doped SnO₂ nanoparticles by a wet chemical method and was characterized by various characterization techniques. PXRD confirmed the presence of the rutile phase for Ce doped SnO₂ nanoparticles. SEM image and elemental mapping showed agglomerated irregular shaped particles and uniform distribution of 5% Ce ions within the SnO₂ lattice, respectively. Ce doped SnO₂ nanoparticles showed antimicrobial activity against E. coli and prevented the growth of bacteria. The nanoparticles were found photocatalytic active and photocatalytic behavior was elucidated by the degradation of Malachite Green dye under UV light irradiation.
