【 摘 要 】

The present work, antibacterial activity of pure and Ceria doped Baddeleyite (ZrO2) nanoparticles (Nps) were synthesized by Co-precipitation method using different bacterial strains (gram positive and gram negative). The obtained samples were characterized by using XRD; SEM and antibacterial study. XRD and SEM confirmed the crystalline nature and morphology of the as synthesized products. The antibacterial studies revealed that doped sample exhibits higher activity compared to pure sample, which can be attributed to an increase of defect concentration (oxygen vacancy) in the sample. In addition, the possible formation mechanism of pure and Ce-doped ZrO2 Nps have also been proposed.
