Preparation method of biological carbon catalytic material for preparing arylamine compound based on hydrogen transfer

The invention belongs to the technical field of preparation of catalytic materials and organic synthesis, and particularly relates to a preparation method of a biological carbon catalytic material for preparing arylamine compounds based on hydrogen transfer, which comprises the following steps: mixing cellulose and dealkalized lignin according to a certain mass ratio to serve as a carbon precursor material; or the waste straw is prepared into powder through a crusher, and the powder is treated to serve as the carbon precursor material; uniformly mixing the carbon precursor material and P2O5 according to different mass ratios, transferring into a hydrothermal kettle, reacting at a certain temperature, cooling to room temperature after the reaction is completed, and performing vacuum drying to obtain a primary carbon material; transferring the corundum boat filled with the primary carbon material into a tubular furnace, performing high-temperature pyrolysis at a controllable temperature, and then naturally cool
