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...
