The copper oxide was prepared by solvo-thermal method and the zinc oxide was prepared by co-precipitation method. The influence of calcinations temperature on copper oxide and the influents of solvents on zinc oxide were examined. The crystalline size, morphology and the functional group analysis were done using X-ray diffraction, scanning electron microscope and Fourier transform infrared spectroscopy. The impact of synthesis methods and its influence in final structure of copper oxide and zinc oxide nanomaterials were explored. Keywords: Copper oxide, Zinc oxide, solvo-thermal, scanning electron microscope. Introduction Nano-sized materials have been attracting great attention due to their outstanding physical and chemical properties 1 . It is well recognized that the phases, sizes, and morphologies of nanomaterials have great influence on their properties and potential applications. The controlled synthesis of nanostructured materials with novel morphologies has received much attention 2 . As a kind of conventional copper oxide (CuO) and zinc Oxide (ZnO) nanomaterials have been used in many fields because of their exceptional properties as well as cost effective. Several novel and effective methods have been developed to synthesize various metal oxides such as CuO and ZnO nanomaterials with various shapes, such as nanorods, nanotubes, and hierarchical superstructure 3-11 . These nanomaterials have superior properties and abundant potential applications in the fields of energy storage device, catalyst, photonic crystals etc., In this work, a simplistic method is used to synthesize copper oxide nanoparticles through high temperature reductive decomposition of CuCl2 with oleic acid (OA) as a solvent, surfactant and capping agent. The variation of reaction temperature influenced the activity between CuCl2 and OA. The OA is not only a reactant, but also a ligand. Another part of this present work describes the preparation of ZnO with well-defined morphologies synthesized via solution route. Moreover the unique properties like structural and optical studies of these CuO and ZnO nanostructures have also been discussed in detail. The paper is arranges as follows: The preparation of CuO and ZnO is given in section 2. The characterization and the corresponding discussions are given in section 3 followed by the conclusion. Experimental Procedure All chemicals are purchased from Sigma Aldrich. The received chemicals are used without further purification. (i) Synthesis of copper oxide nanomaterials: In this synthesis, 2 M of solution is prepared by dissolving CuCl2·2H2O in 100 ml oleic acid under constant stirring for about 8 hours at room temperature. After the stirring process the brown color solution is dried at 150°C. Finally, the oxide powders are calcinated at 400°C and 500°C for 4 hrs. (ii) Synthesis of ZnO nanoparticles: In this method, 0.5 mol/L of Zn(NH3)4 2+ precursor is prepared by mixing zinc acetate and fresh ammonia (pH∼10.5). Zn(NH3)4 2+ precursor solution and the solvents are mixed, to a volume ratio of 1:10, in a vessel under constant stirring
