| titleOfInvention | A kind of preparation method of Ca3Co4O9 nanofiber |
| abstract | The invention discloses a preparation method of Ca 3 Co 4 O 9 nanofibers, comprising the following steps: a. Dissolving cobalt nitrate and calcium nitrate in a mixed solution of absolute ethanol and DMF, and then adding PVP thereinto to obtain static electricity liquid required for spinning; b. preparing fibers by electrospinning; c. drying the obtained fibers, and then sintering them to obtain Ca 3 Co 4 O 9 nanofibers. The grain size of the Ca 3 Co 4 O 9 prepared by the invention is 50-200 nm, the grain size is greatly reduced, the specific surface area is increased, and the thermoelectric performance and the electrochemical performance of the Ca 3 Co 4 O 9 material are greatly improved; The temperature is only 600-700 °C, and the synthesis temperature is significantly reduced, which is beneficial to saving energy. |
