Investigation of Methods and Affecting Factors on the Synthesis of Copper (I) Oxide Nanoparticles in Stable Form

In recent years, monovalent copper oxide (Cu2O) nanoparticles have been used in various industries due to their unique properties. Due to its importance and many applications, common methods of synthesis of these nanoparticles, which are usually done by chemical reduction and sedimentation in an alkaline aqueous medium, have been studied in four groups: precipitation, solvothermal/ hydrothermal, sonochemical and electrochemical. Properties, stability, as well as the performance of this nanoparticle depends on how it is made and the parameters that affect its size, structure, shape, purity and stability. Therefore, the effect of factors such as type of surfactant and precursor, coating and reducing agent, temperature and reaction time, stirring speed of raw materials and concentration of solvent used has been investigated. By increasing the reducing agent concentration, stirring speed, precursor and solvent concentrations to the optimum, the size of the synthetic particles will be smaller.
