A one-pot synthesis of a bimetallic-nitrogen doped carbon-based bifunctional catalyst, as well as its preparation method and applications. This catalyst can catalyze the efficient and selective hydrogenation of biomass feedstocks including bio-based sorbitol, xylitol, cellulose and lignocellulose to produce low-carbon alcohols such as diols. The catalyst proposed in the present invention is prepared from cheap and renewable biomass to obtain porous nitrogen-doped carbon materials, without the requirement of adding nitrogen-containing organic compounds as nitrogen sources for nitrogen doping, thereby being environmentally benign and cost-effective.
