The invention discloses the synthesis and photocatalytic application of a MIL-101 (Fe) photocatalyst with a spindle morphology, and belongs to the technical field of nanomaterials. In the present invention, ferric chloride hexahydrate is used as iron source, terephthalic acid is used as ligand, and in ethylene glycol and N,N-dimethylformamide (DMF) solvent, a solvothermal method is used to synthesize MIL-with special morphology 101(Fe). The preparation method is simple, feasible, economical and environmentally friendly, and the photocatalytic nitrogen fixation and ammonia production of the prepared MIL-101(Fe) photocatalyst with special morphology is 2.6 times that of the traditional MIL-101(Fe). Fe in the MIL-101(Fe) photocatalyst with special morphology plays the role of activating nitrogen gas to enhance the photoreduction ability of the photocatalyst. The special morphology increases the content of iron on the surface, and the morphology is beneficial to the reflection and refraction of light. Thus, the photocatalytic activity is improved, which is of great significance for improving the nitrogen reduction efficiency. |
