| titleOfInvention | Lanthanum-doped tin dioxide hollow porous micro-nanospheres and preparation method and application thereof |
| abstract | The invention relates to the technical field of low-frequency wave-absorbing material preparation, in particular to lanthanum-doped tin dioxide hollow porous micro-nanospheres and a preparation method and application thereof. The micro-nano sphere is prepared from stannous chloride and lanthanum nitrate by an electro-spray method and heat treatment, and the preparation method specifically comprises the following steps: preparing electrospraying precursor liquid from stannous chloride, lanthanum nitrate, N-dimethylformamide, absolute ethyl alcohol and polyvinylpyrrolidone, preparing precursor micro-nano composite spheres by an electrospraying method, and performing heat treatment to obtain the lanthanum-doped stannic oxide hollow porous micro-nano spheres. The obtained micro-nano sphere has better low-frequency (below 8 GHz) wave-absorbing performance. |
