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 Pd9Ag1/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 Pd9Ag1/N‐BB are also carried out, providing strong evidence for the excellent performance of the Pd9Ag1/N‐BB catalyst. The Pd9Ag1/N‐BB displays a great application prospect in catalytic HDO of lignin‐derived compounds.
Biorefinery to fabricate biofuels, chemicals, and materials has attracted much attention. Herein, a highly dispersed non‐noble CoFe immobilized on nitrogen‐doped carbon catalyst is prepared via a template sacrificial method. Owing to the synergetic effect of Co and Fe, the high dispersity of CoFe nanoparticles and large specific surface area, the optimized Co9‐Fe1‐NC catalyst exhibits high activity for the selective hydrogenation of furfural (FAL) to furfuryl alcohol (FOL). Hundred percentage conversion of FAL and 99% selectivity of FOL are obtained at 120 °C with 1 MPa H2 for 4 h, which is superior to most of the reported nonprecious catalysts. Moreover, the Co9‐Fe1‐NC catalyst can also catalyze the hydrogenation of nitro and carbonyl compounds efficiently. The mechanism of hydrogenation of FAL is revealed by density functional theory calculations. This work provides a promising synthetic strategy for the rational structural design of efficient selective hydrogenation catalysts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
