Abstract Morphology control have been significantly highlighted in the field of catalysis because each facet of crystalline particle exhibits unique properties. Even Co3O4 particles with spinel crystal structure have been attracted for promising candidate in the field of battery, catalyst and magnet, there search on morphology of Co3O4 particle shape been rarely reported. In this work, we report facile synthesis of Co3O4 particles with various morphologies. Co3O4 particles was simply synthesized via hydrothermal process using cobalt precursor, NaOH, polyvinylpyrrolidone and solvent. Morphologies of each samples were controlled with concentration of polyvinylpyrrolidone and solvent. Also, we experimented to obtain a various shape of Co3O4 particles by tuning reaction time. As a preliminary research, we report various shape of Co3O4 and characterize the products by scanning electron microscope, transmission electron microscope and UV-Vis spectroscopy.
