Abstract

The invention discloses a biomass carbon-based material high-load nano-metal catalyst, as well as a preparation method and application thereof. The catalyst is prepared by soaking shaddock peel powderin a nitrate solution having a certain concentration, drying and calcining, metal simple component serves as the active component, and organic carbon serves as the carrier; the nitrate is ferric nitrate, cobalt nitrate, nickel nitrate or copper nitrate; and the metal simple component is iron, cobalt, nickel or copper. The catalyst has the characteristics of environment-friendly raw materials, simple preparation process and high hydrogenation selectivity, has a good effect when being applied to a hydrogenation reaction of biomass derivatives, for instance, the furfuryl alcohol yield at a relatively low temperature of 170 DEG C can be 98,9 percent when the furfuryl alcohol is prepared by a furfuryl alcohol selective hydrogenation reaction.
