Non-noble metal biomass charcoal composite material as well as preparation method and application thereof

The invention discloses a non-noble metal biomass charcoal composite material capable of catalytically hydrogenating p-nitrophenol into p-aminophenol, a preparation method of the non-noble metal biomass charcoal composite material and application of the non-noble metal biomass charcoal composite material in catalytically hydrogenating p-nitrophenol into p-aminophenol. The preparation method comprises the following steps: adding a metal precursor salt solution into a glucosamine hydrochloride solution, fully stirring, adding melamine, and stirring to form a uniformly dispersed suspension; the metal precursor salt is at least one of Fe < 3 + > salt, Co < 2 + > salt and Ni < 2 + > salt; and heating the suspension liquid under stirring to evaporate the solvent to dryness, and pyrolyzing the obtained solid mixture in an inert atmosphere at 600-900 DEG C to obtain the non-noble metal biomass charcoal composite material capable of catalytically hydrogenating p-nitrophenol into p-aminophenol. 本发明公开了一种可催化氢化对硝基苯酚为对氨基苯酚
