Upgrading renewable biomass into high‐valued biofuels and chemicals is highly desirable, however, still remains a challenging task. Hydrodeoxygenation (HDO) is regarded as an effective and promising approach for biorefinery. Herein, the bipyridine ligand with strong metal anchoring capacity is used as a monomer to fabricate porous organic framework (POF) materials. The bipyridine‐based POF (named as N‐BB) serves as an HDO catalyst support to stabilize PdAg bimetallic nanoparticles. Due to the abundant porous structure of the N‐BB support, good dispersity of PdAg nanoparticles, large specific surface area, and synergetic effect of Pd and Ag, the prepared Pd 9 Ag 1 /N‐BB catalyst exhibits high activity and stability for the HDO of lignin‐derived molecules. In addition, the kinetic studies of the hydrogenation of vanillin over Pd 9 Ag 1 /N‐BB are also carried out, providing strong evidence for the excellent performance of the Pd 9 Ag 1 /N‐BB catalyst. The Pd 9 Ag 1 /N‐BB displays a great application prospect in catalytic HDO of lignin‐derived compounds.
