Effect of Zr doping on photoantioxidant and antibiofilm properties of CeO NPs fabricated using aqueous leaf extract of Pometia pinnata.

Synthesized cerium oxide nanoparticles (S-CeO NPs) and 1%, 5% and 10% zirconium doped CeO (Zr-doped CeO) NPs were fabricated using aqueous leaf extract of Pometia pinnata. The synthesized NPs were characterized using standard techniques which confirmed successful synthesis of NPs with particle size ranging from 12 to 23 nm and band gap energy of 2.54-2.

Green-synthesized CeO nanoparticles for photocatalytic, antimicrobial, antioxidant and cytotoxicity activities.

Cerium oxide nanoparticles (CeO2 NPs) are a sought-after material in numerous fields due to their potential applications such as in catalysis, cancer therapy, photocatalytic degradation of pollutants, sensors, polishing agents. Green synthesis usually involves the production of CeO2 assisted by organic extracts obtained from plants, leaves, flowers, bacteria, algae, food, fruits, etc. The phytochemicals present in the organic extracts adhere to the NPs and act as reducing and/or oxidizing agents and capping agents to stabilize the NPs, modify the particle size, morphology and band gap energy of the as-synthesized materials, which would be advantageous for numerous applications.

Green synthesis of CeO and Zr/Sn-dual doped CeO nanoparticles with photoantioxidant and antibiofilm activities.

Cerium oxide (CeO2) and 1%, 5% and 10% zirconium/tin-dual doped CeO2 nanoparticles (Zr/Sn-dual doped CeO2 NPs) were synthesized using an aqueous leaf extract of Pometia pinnata. By using UV-visible diffuse reflectance spectroscopy, the band gap energies of these materials were found to be in the range of ∼2.49 to 2.
