Abstract: Copper oxide nanoparticles have been received attraction due to their unique properties and potential future applications. In present work nanostructure Copper (II) oxide (CuO) spherical nanoparticle synthesized by solution combustion method and the influence of different fuel and condition on the properties of CuO particle was investigated. Crystalline phase and size indicated by applying XRD and particle size distribution studied further using DLS. Scanning electron microscopy (SEM) was used for morphological study and EDAX analysis shows composition of CuO particles. Nanostructure of copper (II) oxide particle studied further by Transmission electron microscopy (TEM) and selected area electron diffraction (SAED) applied for detail study on crystalline structure of particles. Introduction Copper (II) oxide nanoparticle known as p-type semiconductor, with a direct band gap [1], is a low-cost material for photovoltaic devices [2], and it has been used widely in variety of applications such as: electrode materials for lithium-Iron battery[3],solar-energy transformation [4], gas's sensor [5]. During the past decade, different types of CuO nanostructures have been prepared, which involve multiple steps that were not efficient. Properties of materials at nanoscale, strongly depend on their shape and dimensions [6-9]. Recently Copper Oxide nanostructured, such as: nanotubes, nanorods [10], nanowires [11], nanorings, nanoribbones [12] and nanobelts have received attraction due to their fundamental importance and potential future applications [13-16]. Number of techniques such as: Chemical Vapor Deposition, Physical Vapor Deposition, Sol-gel, hot-soap, pyrolysis, and spray pyrolysis methods for the preparations of nanoparticles have been developed [17]. All these techniques require special equipments [18]. Industrial processes need to be time efficient, low-cost, continuous operation and high production rate. Solution Combustion synthesis (CS) is a time-consuming and cost-efficient method to produce various industrially metal oxides [19]. Solution method has been attracted more interesting as a safety and environmental friendly route for the large-scale production of CuO nanostructures [20].Preparation of spherical homogenous CuO nanoparticle, using sono-chemical method also needed calcination at high temperature (600-700 o C) [21]. In this work copper (II) oxide nanostructure was synthesized and influence of fuel and condition in combustion synthesize on size, morphology, and crystallinity of CuO was investigated.
