Abstract

The Chenopodium album plant was collected and the fresh plant extract plays a key role in zinc oxide nanoparticle synthesis. The reduction of Zn2+ions to ZnO NPs by aqueous leaf extract of Chenopodium album was visually observed by color variation in the reaction mixture. The gradual color change in solution from light green to pale yellow. This indicates that the metal acetates were reduces to form its respective nanoparticles. The UV-visible absorption peak arises from 320-380 nm denote the development of ZnO NPs. In our study, the extreme absorption peak seemed at 374 nm directs the individual SPR band for ZnO NPs with lesser particle size. The FT-IR spectrum noted, Scanning Electron Microscopy (SEM) investigation was performed to govern the size and morphology of the green synthesized ZnO NPs by Chenopodium album (aqueous leaf extract). The elemental composition of the synthesized ZnO NPs was confirmed by EDX analysis. The XRD pattern of aqueous leaf extract of Chenopodium album derived ZnO NPs. In conclusion the zinc oxide nanoparticle was synthesized using fresh leaf extract of Chenopodium album. The synthesized nano particle was characterized and confirmed using UV-Visible, FT-IR, XRD, FE-SEM, EDX and SEM mapping analysis, the results showed that ZnO Nps were synthesized properly.
