MOF基Ni/Cu双金属催化剂催化糠醛制备环戊醇
Preparation of Cyclopentanol From Furfual Catalyzed by MOF-based Ni/Cu Bimetallic Catalyst
摘要
Abstract
The catalytic hydrogenation of furfural to cyclopentanol was investigated using water as solvent and metal-organic framework(MOF)supported nickel and copper nanoparticles(MOF-Ni/Cu)as a catalyst.The effects of catalyst metal ratio,reaction temperature,reaction time and hydrogen pressure on the furfural catalytic hydrogenation reaction were investigated.The surface morphology and structure of the catalyst were characterized by X-ray diffraction and scanning electron microscopy.The acidity of the catalyst was analyzed by NH3-TPD,and the element valence of the catalyst was analyzed by X-ray photoelectron spectroscopy.The analysis showed that in the MOF-Ni/Cu catalyst,when the molar ratio of Ni to Cu was 1∶1,the specific surface area and total acidity of the MOF-Ni/Cu catalyst were relatively high.During the process of preparing the catalyst with metal loading,a Ni-Cu alloy was synthesized,and no oxides of Ni and Cu were observed.Both Ni and Cu elements existed in the catalytic reaction process in atomic form,and there was a synergistic effect between the alloy metals,with charge transfer occurring on the alloy particles.The research results showed that compared with the single metal MOF-Ni and MOF-Cu,bimetallic MOF-Ni/Cu had higher catalytic activity.When the molar ratio of metal Ni and Cu was 1∶1,under the conditions of water as medium,a reaction temperature of 220℃,a reaction time of 2 h,and a hydrogen pressure of 2 MPa,the conversion rate of furfural was more than 99%and the yield of cyclopentanol was 59%.The catalyst had good reusability.After being reused for five times,the yield of cyclopentanol remained stable at about57%,showing no significant decline compared with the initial reactivity.关键词
