Copper-magnesium co-doped carbonized wood sponge material, preparation therefor, and application thereof, and method for converting plastics into fuel based on fenton-like system

A method for converting plastics into fuel based on a Fenton-like system, comprising the following steps:

• mixing a plastic sample, a catalyst, persulfate and water, performing a hydrothermal reaction, and performing solid-liquid separation of an obtained product to obtain a plastic conversion product,
• the catalyst being a copper-magnesium co-doped carbonized wood sponge material, and
• a preparation method for the copper-magnesium co-doped carbonized wood sponge material comprising the following steps:
• compounding a wood raw material with a dopamine solution, and performing polymerization to obtain a wood material attached with polydopamine (PDA),
• performing first impregnation of the wood material attached with PDA in a mixed metal salt solution, adding a 2-methylimidazole solution, performing second impregnation, and sequentially performing pre-freezing and freeze-drying of an obtained material to obtain a freeze-dried material, metal ions in the mixed metal salt solution comprising copper ions and magnesium ions, and
• performing calcination of the freeze-dried material to obtain the copper-magnesium co-doped carbonized wood sponge material.
