Summary: | Antibacterial activity of C. procera flower extract and biosynthesized CeO2-NPs.
[Display omitted]
•Synthesis of CeO2-NPs by biological methods using Calotropis procera flower extract.•The synthesized CeO2-NPs were characterized by UV–Visible, XRD, HR-TEM and FT-IR.•Effective photocatalytic degradation of MO dye with 98% in 50 min under sunlight irradiation.•Excellent antibacterial activities shown by biosynthesized CeO2-NPs using Calotropis procera flower extract.
The eco-friendly synthetic approach for preparing CeO2-NPs using C. procera flower extract. The synthesized CeO2-NPs were studied for their UV–Vis, XRD and HR-TEM. The X-ray diffraction studies confirmed the cubic structure of synthesized CeO2-NPs with an average crystallite size of 7 nm. High Resolution Transmission Electron Microscope (HR-TEM) images showed that the CeO2-NPs possessed spherical shape and particle size of 21 nm. The photocatalytic degradation of methyl orange (MO) dye under sunlight irradiation by biosynthesized CeO2-NPs was analyzed. The synthesized CeO2-NPs exhibited 98% degradation activity against MO dye. Furthermore, antibacterial activity of C. procera flower extract and biosynthesized CeO2-NPs were studied. The biosynthesized CeO2-NPs exhibits a important antibacterial activity against Gram negative bacteria Escherichia coli and Pseudomonas aeruginosa than Gram positive bacteria. |
