Co-precipitation methods for the synthesis of metal oxide nanostructures

Synthesis methods play an important role in controlling the structure and morphology of nanomaterials. Basically, synthesis method used for producing metal oxide or other nanostructures either in film or in power form should be simple, cost effective, easy to handle and should be able to provide a mass production of the product. Coprecipitation method is being studied to large extent especially for the synthesis of iron oxide-based nanomaterials on mass scale. So this chapter elaborates the synthesis mechanism of co- precipitation method for metal oxide-based nanoparticles. It also throws light on the synthesis of different metal oxides and how certain flaws like agglomeration can be minimized with modification in the traditional synthesis route of the co-precipitation method. In co-precipitation method, the powder form of product is obtained via supersaturation mechanism.
