| titleOfInvention | Ferrous disulfide taking MOF as precursor and preparation method thereof |
| abstract | The invention belongs to the field of material preparation, and particularly relates to ferrous disulfide taking MOF as a precursor and a preparation method thereof. The structure of the ferrous disulfide is MOF type, and a carbon coating layer is arranged on the surface of the material; the preparation method comprises the following specific steps: step (1): dissolving iron salt, a carbon source, a precipitator, a dispersing agent and the like into a solvent, and preserving the solution in an oven for a certain time to obtain a Fe-based precursor; step (2): dissolving the Fe-based precursor obtained in the step (1) and carboxylic acid in a solvent according to a ratio, and preserving heat in an oven to obtain a Fe-MOF precursor; and (3): and (3) calcining the Fe-MOF precursor and the sulfur powder obtained in the step (2) in an inert atmosphere according to a ratio to obtain the MOF ferrous disulfide with carbon-coated surface. The method of the invention can regulate and control the particle size and the pore structure of the precursor. The FeS2 prepared by the method is applied to the cathode material of the sodium-ion battery, so that the cycle life of the battery is effectively prolonged, and the battery has good electrochemical performance. |
