Vedak Institute of Technology, Tala, University of Mumbai, Maharashtra, India ABSTRACT Copper oxide nanoparticles (CuONPs) synthesized by a completely environmentally safe and facile process using Ziziphus mauritiana L. aqueous plant extract as an effective stabilizing agent. Phytochemical screening of the fresh aqueous leaves extract showed the presence of coumarins, tannins, saponins, flavonoids, and glycosides. The synthesized CuO nanomaterial was characterized by XRD, SEM, EDX, TEM and surface area. This green synthesis route indicates that, it is efficient method than chemical method. Keywords: Nanotechnology, Ziziphus mauritiana L., CuONPs, Phytochemical screening. I. INTRODUCTION Nowadays CuONPs have generated a great deal of interest, especially in the field of gas sensing [1], catalysis [2] and biomedical [3] because of their remarkable applications. These CuONPs fabricated using different synthetic routes such as ionic liquid assisted, microwave irradiation, sonochemical, electrochemical, sol-gel technique and thermal treatment [4-9] have been reported. Nevertheless, these routes have some drawbacks like the use of toxic chemical, use of acrimonious synthesis conditions like high temperature and requirement of external additives during the reaction time. Hence there is limited scope for the development of efficient, environmentally safe and additive free synthesis of CuONPs. Currently plant extract mediated nonmaterial synthesis is getting lot of attention with several advantages offered by chemical methods [10-12]. The scrutiny of the literature revealed some notable plant extract used for facile synthesis of CuO-NPs. For example, Rauvolfia serpentina [13], Leucaena leucocephala [14], Calotropis gigantean [15], Aloe barbadensis [16], Ficus religiosa [17], Albizia lebbeck [18] and Acanthospermum hispidum [19] have been reported. Ziziphus mauritiana L. (Figure 1) belongs to family Rhamnaceae is an annual plant which grows in tropical and sub-tropical regions of world. Different parts of this plant have been used in the traditional medicine for the treatment of different ailments. In this study, we report the use of Ziziphus mauritiana L. as stabilizing and reducing agent in the ecofriendly synthesis of CuONPs. Figure 1. Leaves of Ziziphus mauritiana L. II. MATERIALS AND METHODS 2. 1. Materials Copper acetate monohydrate was used as a precursor. The fresh leaves of Ziziphus mauritiana L. were sourced from Sangamner college campus, Maharashtra, India. The collected leaves were washed with deionized water, cut into small pieces. All glassware’s are washed with distilled water and acetone and dried in oven before use.
