Ni@C@CNT catalyst derived from CNT doped Ni‐MOF for furfural hydrogenation to tetrahydrofurfuryl alcohol

Abstract

Conversion of biomass-derived furfural platform compound to value-added tetrahydrofurfuryl alcohol (THFL) molecule is a sustainable route, and an efficient nonnoble metallic catalyst is a key factor for this reaction. In this work, Ni@C@CNT composite as a highly effective catalyst for hydrogenation of furfural to tetrahydrofurfuryl alcohol was synthesized by one-step pyrolysis of Nicentered metal organic framework (Ni-MOF) doping with carbon nanotube (CNT). For comparison, Ni@C catalyst derived directly from Ni-MOF was also synthesized. The characterization results show that the doping of CNT promotes high dispersion of active sites and formation of Ni 3 C phase which has Pt-like catalytic activity. Therefore, the obtained Ni@C@CNT exhibited excellent activity in furfural hydrogenation (99.1% furfural conversion and 94.7% THFL yield at 120 C, 4 h, 4-MPa initial hydrogen pressure). Ni@C@CNT also shows good stability in reuse test. Current work presents a facile method for preparation of nonnoble metallic catalysts with high efficiency.

Advancements of MOFs in the Field of Propane Oxidative Dehydrogenation for Propylene Production

“…A higher conversion rate indicates that the catalyst can more effectively promote the reaction while reducing side reactions and catalyst loss. The conversion rate can be determined using methods such as colorimetry [ 77 , 78 ], gas chromatography [ 79 , 80 , 81 ], and nuclear magnetic resonance [ 82 ]. TOF [ 83 ]: TOF refers to the number of reactant molecules converted per active site on the catalyst per unit time.…”
