Simple methods of synthesis of copper oxide, zinc oxide, lead oxide and barium oxide nanoparticles


Nano meter sized metal oxide draws much attention because of their unusual physical and chemical properties and extremely large specific area. While most micro structural materials have similar properties to the corresponding bulk materials, the properties of materials with nano meter dimension are significantly different from those of atoms and bulk. This is mainly due to the nano-meter size of the materials which render them (i) large fraction of surface atoms; (ii) high surface energy; (iii) spatial confinement; (iv) reduced imperfections, which do not exist in the corresponding bulk materials. Nano metal oxides have a wide range of application in the field of electronics, fuel cells, batteries, agriculture, food industry medicines etc. Various methods have been reported for the synthesis of metal oxide nano particles in which stabilizers such as polymers and surfactants have been used to prevent the particles from aggregation. The present study aimed at the synthesis of CuO, ZnO, BaO and PbO nano particles using simple chemical precipitation and hydrothermal techniques and their characterization using XRD and SEM.
