| titleOfInvention | Composite metal oxide hollow multi-shell material and preparation method and application thereof |
| abstract | The invention provides a composite metal oxide hollow multi-shell material, a preparation method and application thereof, wherein the method comprises the following steps: dispersing carbon spheres in a first metal salt solution by using the carbon spheres prepared by a hydrothermal method as a template, and carrying out hydrothermal enhanced adsorption and drying to obtain a solid precursor; dispersing the obtained solid precursor in a second metal salt solution, adsorbing and roasting to obtain the composite metal oxide hollow multi-shell material. According to the invention, the relative content of the narrow-bandgap metal oxide attached to the inner shell layer of the metal oxide hollow sphere is high, and the relative content of the wide-bandgap metal oxide attached to the outer shell layer is high by a two-step adsorption method, so that the sequential absorption of light of each waveband in a solar spectrum is realized. |
