| titleOfInvention | Metal or metal oxide with hierarchical structure and preparation method of metal or metal oxide |
| abstract | The invention discloses a metal/metal oxide with a hierarchical structure and a preparation method of the metal/metal oxide. The method comprises the following steps: (1) a polyvinylpyrrolidone solution is compounded, and electrostatic spinning is performed; (2) mechanical erosion is performed on a fiber surface so as to obtain a fiber template with a hierarchical structure; (3) metals or metal oxides are spurted on the surface of the fiber template with the hierarchical structure; (4) materials of the fiber template are removed by utilizing a high-temperature annealing method. Hierarchical structure material prepared by the preparation method disclosed by the invention is a hollow metal or metal oxide with a branch structure. The diameter of a branch can be controlled by regulating time for the deposition of the material, and the length of the branch can be controlled by changing time for the mechanical erosion of oxygen plasmas. The method disclosed by the invention is simple and convenient to prepare the hierarchical structure with high specific surface area, and has a wide application prospect in many fields, such as gas sensors, catalysis and surface enhancement raman scattering. |
