| Abstract: | 3D flowerlike Co3O4 nanostructures were prepared by a microwave-assisted hydrothermal method,which is a rapid,template-free,and low cost method.The product is obtained in two minutes using all inorganic precursors.The precursor concentration and gradual hydrolysis of urea determine the morphology of Co3O4 nanostructures.These flowerlike Co3O4 nanostructures have high surface area and expose largely active(110) planes,leading to relative high catalytic activity in CO oxidation. |
