Green Fabrication and Characterization of Zinc Oxide Nanoparticles Using Celery Leaf Extract

Abstract

The development of novel theoretical and experimental techniques in nano-science always lead to proactive opportunity for innovative nano-scaled materials. Materials with nano-structure are known to bridge the smallest atoms and the largest molecules of bulk materials through which many enhanced properties can be attained. In an attempt to minimize environmental hazards, reducing the use of toxic non-degradable products and moving towards developing an environmentally safe material. This paper will present the synthesis of bio-based nano-sized ZnO particles prepared from celery leaf plant extract as reducing/stabilizing agent and zinc chloride metal salt as metal ion precursor that chemically altered into metal oxides nanoparticles. “Co-precipitation” method was used to synthesize the ZnO nanoparticles at room temperature. To properly characterize the synthesized ZnO nanoparticles, four different tests were conducted namely, XRD, FE-SEM, EDS and AFM. The characterization analysis for the synthesized ZnO nanoparticles indicated average particles size of 35 nm. Also, the morphology analysis indicated the formation of ZnO nanoparticles having shape of hexagonal wurtzite nanocrystals compatible with the Joint Committee on Powder Diffraction Standards (JCPDS) card no. (36-1451) for pure ZnO nanoparticles. The produced ZnO nanoparticles from green synthesis process can be directly used as an eco-friendly additive in many industrial applications.
