The invention belongs to energy and chemical industry and particularly relates to a method of synthesizing imine and amine compounds by means of borrowing-hydrogen reduction coupling by using a nitrogen-doped hierarchical-porous biomass-based carbon material supported catalyst. The method includes the steps of: under a seal reaction condition, adding a nitro-aromatic hydrocarbon compound, benzyl alcohol compounds with different substituent groups, the supported catalyst, methylbenzene and potassium tert-butoxide; performing a reaction at 50-150 DEG C for 4-24 h, cooling the product to room temperature and filtering a reaction liquid to obtain the imine compound represented in the formula (1) or the amine compound represented in the formula (2). The raw materials of the catalyst are regenerable resources, are widely distributed, are green and environment-friendly, are easy to prepare and abundant in sources, and are low in cost; the catalyst can be recycled without deactivation and is stable to air, water and heat. By means of the supported metal catalyst, the conversion rate of the borrowing-hydrogen reduction coupling reaction on the nitro-compound and alcohol to prepare the iminecompounds is higher than 99%, and yield can reach 90-60%; the conversion rate of same to prepare the amine compounds is higher than 99%, and yield can reach 90-60%.
