Preparation and Its Catalytic Performance of Pd/NH2-MIL-101/CoFe2O4
Suzuki coupling reaction is an important C-C bonding reaction,for which transition metals and precious metals are mainly used as catalysts,among which the supported Pd catalysts exhibit better catalytic performance.Metal-organic skeleton(MOF)is an ideal support for metal catalysts.However,the nano-scale metal-organic skeleton material is not easy to separate and recycle.Magnetic nanoparticles are easy to be separated and located,thus magnetic MOFs prepared by combing the MOFs with magnetic nanoparticles have advantages of both MOFs material and magnetic compounds.In this paper,using the magnetic metal-organic framework material NH2-MIL-101/CoFe2O4 as the carrier and stabilizer,magnetic composites of Pd/NH2-MIL-101/CoFe2O4 with highly dispersed metal Pd nanoparticles were prepared.The magnetic composite exhibited high activity and selectivity in the Suzuki coupling reaction,which can be recovered and reused through simple magnetic separation.Moreover,it can be reused three times without obvious loss of activity.This work provides a new solution for designing novel heterogenous catalysts.
