Embodiment 1
[0042] At room temperature, add 0.80 g of 2-methylimidazole to 20 mL of methanol solution stirred at a constant speed, and stir at a constant speed for 30 minutes to fully dissolve to obtain solution A; add 0.27 g of nitric acid hexahydrate to the 30 mL of methanol solution stirred at a constant speed Zinc, fully stir the solution to be transparent, then add 5mg MIL-101(Fe) and stir until the solution is light orange, then add 50mg phosphotungstic acid until the solution is evenly mixed to obtain solution B; stir solution A slowly Adding it into solution B, stirring at a constant speed at room temperature for 24 hours, an orange-red precipitate with milky white was obtained, which was centrifuged, dried and ground to obtain a powdery precursor MIL@ZIF-HPW sample. Under the protection of inert gas and high-purity nitrogen, the MIL@ZIF-HPW prepared above was calcined at 700°C to obtain a magnetic core-shell structure porous carbon material, which was named W@MZC-50; the obtained ...

Under the protection of inert gas and high-purity nitrogen, the MIL@ZIF-HPW prepared above was calcined at 800°C to obtain a magnetic core-shell structure porous carbon material, which was named W@MZC-50; the obtained ...
Embodiment 3
[0046] At room temperature, add 0.80 g of 2-methylimidazole to 20 mL of methanol solution stirred at a constant speed, and stir at a constant speed for 30 minutes to fully dissolve to obtain solution A; add 0.27 g of nitric acid hexahydrate to the 30 mL of methanol solution stirred at a constant speed Zinc, fully stir the solution to be transparent, then add 5mg MIL-101(Fe) and stir until the solution is light orange, then add 50mg phosphotungstic acid until the solution is evenly mixed to obtain solution B; stir solution A slowly Adding it into solution B, stirring at a constant speed at room temperature for 24 hours, an orange-red precipitate with milky white was obtained, which was centrifuged, dried and ground to obtain a powdery precursor MIL@ZIF-HPW sample. Under the protection of inert gas and high-purity nitrogen, the MIL@ZIF-HPW prepared above was calcined at 900°C to obtain a magnetic core-shell structure porous carbon material, which was named W@MZC-50; the obtained ...
