The main aim of this work is rapid synthesis of Co3O4 nanoparticles by solution combustion synthesis and its characterization by IR and PXRD. Co3O4 is one of the most thoroughly investigated metal oxide nanoparticles. The reagents used for this work are Co(NO3)2.6H2O (Merck) and Urea (BDH chemicals) of analytical grade .Through this method Co3O4 with different morphologies such as nanospheres, nanocube, nanofiber, and mesoporous structures have been prepared. Rapid and Easy synthesis of cubic spinel phase of Co3O4 nanoparticles of Crystallite size 27.02 nm portrays the efficiency of the method. The properties of newly synthesized Co3O4 strongly depend on their morphologies and structures, including crystal sizes, orientations etc. From this work it is clear that Cobalt Oxide nanoparticles can exhibit unique physical and chemical properties due to their limited size and a high density of corner or edge surface sites. As an important magnetic p-type semiconductor, Co3O4 is of special interest due to its potential applications as sensors, heterogeneous catalysts, electrochromical devices, nano submarines and magnetic materials. Co3O4 Nanomaterials having wide range of applications in the field of electronics, agriculture, food industry, and medicines, etc.
