Embodiment 1

[0052]Weighed 74.4 mg of ferrocene and 2380.0 mg of zinc nitrate hexahydrate and dissolved them in 60 mL of anhydrous methanol to obtain a clear solution A. Simultaneously, 2628.0 mg of 2-methylimidazole was dissolved in 30 mL of absolute methanol to obtain a clear solution B. A and B were mixed and reacted for 10 h at room temperature with stirring. After the reaction, the obtained dispersion was centrifuged at 3000rpm / min for 30min, and the light yellow precipitate was collected, washed three times with anhydrous methanol and anhydrous ethanol solutions, and then vacuum-dried at 40°C for 24h to obtain a ferrocene-loaded ZIF- 8 metal organic framework powder. Weigh 500mg ferrocene-loaded ZIF-8 metal-organic framework powder into a covered quartz boat, pass through Ar, heat from room temperature to 900°C at a rate of 2.5°C / min and hold for 24h. After cooling, the obtained black powder was washed with 0.5 mol / L dilute sulfuric acid for 8 hours, and then vacuum-dried to obtain...

Abstract

The invention discloses preparation and application of an iron-nitrogen co-doped porous carbon material. Ferrocene, zinc nitrate and 2-methylimidazole are weighed and dissolved in methanol, ferrocene-loaded ZIF-8 metal organic framework powder is prepared at normal temperature, and then high-temperature treatment is performed in a protective atmosphere to obtain the iron-nitrogen co-doped porous carbon material. The iron-nitrogen-carbon material prepared by the preparation method disclosed by the invention has excellent sewage treatment performance.

Description

technical field [0001] The invention relates to a porous carbon material in the field of heterogeneous catalysis and a preparation method thereof, in particular to the preparation of an iron-nitrogen co-doped porous carbon material and its application in water pollution treatment. Background technique [0002] With the development of society, the increasingly serious problem of water pollution has become one of the most urgent problems to be solved. Among them, organic pollutants (such as antibiotics, organic dyes, plastic additives, volatile organic compounds, pesticides, etc.) Stability and thus difficult to be removed by traditional methods such as filtration, adsorption and biodegradation. At present, sulfate radical advanced oxidation technology has attracted the attention of many scholars due to its advantages of simple operation, high degradation efficiency, and good safety. [0003] Sulfate radical advanced oxidation technology mainly uses catalysts (transition meta...
