Catalyst for preparing 1,5-pentanediol via hydrogenolysis of tetrahydrofurfuryl alcohol, method and application thereof

The present invention provides a method for preparing 1,5-pentanediol via hydrogenolysis of tetrahydrofurfuryl alcohol. The catalyst used in the method is prepared by supporting a noble metal and a promoter on an organic polymer supporter or an inorganic hybrid material supporter, wherein the supporter is functionalized by a nitrogen-containing ligand.
