Heterogeneous Nickel Catalysts Derived from 2D Metal-Organic Frameworks for Regulating the Selectivity of Furfural Hydrogenation

Hydrolysis of the biomass platform compound furfural can produce a bulk of fine chemicals because of its multiple functional groups. Developing an efficient catalytic system to regulate the process toward some desirable products has always been a hot research area. Herein, the novel Ni-based catalysts (Ni-MFC-X, X = 300, 400...800) synthesized by pyrolysis of the 2D Ni-based metal-organic framework (MOF) in the temperature range 300-800 degrees C show good performance for selective hydrogenation of furfural (FUR). Interestingly, the calcination temperature of the MOF precursor plays an important role in hydrogenation of furfural with controllable selectivity toward furfuryl alcohol (FOL) and tetrahydro FOL (THFOL). Ni-MFC-500 affords us 92.5% conversion of furfural and 59.5% selectivity of FOL. Ni-MFC-700 can promote hydrogenation of furfural with 91.8% conversion and 51.0% selectivity of THFOL. Furthermore, the stability of as-obtained NiMFC-500 and Ni-MFC-700 was also very impressive in this reaction system.
