Phyto-mediated green synthesis of CeO2-ZnO nanoparticles using glycosmis mauritiana leaf extract: Antibacterial activity and photodegradative applications

A simple novel green synthesis of the nano compound cerium oxide doped with zinc oxides (CeO2-ZnO) was produced with a reduction agent of glycosmis mauritiana leaf extracted. The compounds synthesized are characterized by x - ray diffraction, UV, DRS and TEM. The results show that the prepared materials were superior in performance as compared to unoped ZnO and CeO2 particles, due to alternation in band gap, surface adsorption and enhanced photoresponsive. The photocatalytic efficiency of the CeO2-ZnO series was evaluated against Acid black 1 and the antibacterial properties were checked against the clinical bacteria strains. All findings showed that CeO2-ZnOs' photocatalytical and antibacterial activities with various CeO2 material are superior to the pure ZnO activities. (c) 2019 Elsevier Ltd. All rights reserved.

Automated summary

A simple green synthesis method was used to produce cerium oxide doped with zinc oxides (CeO2-ZnO) nano compounds using glycosmis mauritiana leaf extract as a reduction agent. The synthesized compounds were characterized using x-ray diffraction, UV, DRS, and TEM. The results showed that the prepared materials exhibited superior performance compared to pure ZnO and CeO2 particles, attributed to changes in band gap, surface adsorption, and enhanced photoresponsiveness. The photocatalytic efficiency of the CeO2-ZnO series was evaluated against Acid black 1 and the antibacterial properties were tested against clinical bacteria strains, demonstrating that the CeO2-ZnOs with various CeO2 materials exhibited higher photocatalytic and antibacterial activities than pure ZnO.
