Organodiphosphonate Metal‐Organic Frameworks Derived Ni‐P@C Catalyst for Hydrogenation of Furfural

Tetraethyl p‐xylenediphosphate is used as the organic ligand to prepare the Ni−P‐MOFs material belonging to the category of organic phosphoric acids, through pyrolysis and in‐situ reduction reaction of Ni−P‐MOFs material during the high‐temperature carbonization process, Ni−P@C catalyst with graphitized carbon‐covering Ni2P particles is prepared. Compared with Ni−P catalyst prepared through coprecipitation method, Ni−P@C catalyst prepared with Ni−P‐MOFs material can obviously decrease the formation temperature of Ni2P active phase and retain the schistose morphology of the Ni−P‐MOFs material, which is of high specific area, and meanwhile effectively suppresses the agglomeration of Ni2P particles. It is indicated by research on furfural hydrogenation performance that, Ni−P@C catalyst presents a high activity and stability in furfural hydrogenation. Products of furfural hydrogenation catalyzed by Ni−P@C catalyst mainly contain furfuryl alcohol, 2‐methylfuran and 2‐methyltetra hydrofuran, and the reaction temperature and reaction time have great influence on the distribution of products. The carbon‐covering structure of Ni−P@C catalyst can effectively protect the active components of Ni2P, thus presenting a high stability and good reusability. Ni−P‐MOFs material was prepared using tetraethyl p‐xylenediphosphate as the organic ligand. Ni−P@C catalyst with graphitized carbon‐covering Ni2P particles was prepared by pyrolysis and in‐situ reduction method using Ni−P−MOFs material as the precursor. Ni−P@C catalyst presented a high activity in furfural hydrogenation, and the selectivity of reaction products greatly dependent on the reaction temperature and reaction time.
