| titleOfInvention | Boron-doped LaCoO3Bifunctional catalyst, preparation method and application thereof |
| abstract | The invention relates to boron-doped LaCoO 3 A bifunctional catalyst, a preparation method and application thereof. The preparation method comprises the following stepsThe method comprises the following steps: s1: dissolving lanthanum salt and cobalt salt, adding a chelating agent to obtain a mixed solution, adjusting the pH of the mixed solution to 7.0-10.0, and reacting at 80-110 ℃ under stirring to obtain sol-gel; s2: calcining the sol-gel at 200-300 ℃ for 4-6 h, and then heating to 600-900 ℃; calcining for 2-5 h to obtain a perovskite precursor; s3: mixing the perovskite precursor with a boron source, and calcining at 300-600 ℃ for 2-5 h to obtain boron-doped LaCoO 3 A bifunctional catalyst. The invention prepares LaCoO by using a sol-gel method 3 The perovskite material is doped with non-metallic element boron to regulate and control the microstructure of the perovskite material, so that the catalyst with high ORR and OER catalytic activity is prepared and applied to new energy technologies such as metal-air batteries, fuel batteries and the like. |
