A new cobalt metal–organic framework as a substrate for Pd nanoparticles applied in high-efficiency nitro phenol degradation and cinnamaldehyde hydrogenation

Abstract

In recent years, attributed to the excellent catalytic performance of precious metal materials, metal nanoparticles@MOF catalyst has been a popular research direction. Herein, we have synthesized a new 3D cobalt metal–organic framework [Co(TATAB)(344-pytpy)·DMF]_n(H₃TATAB = 4,4′,4″-s-triazine-1,3,5-triyltri-p-aminobenzoic acid; 344-pytpy = 4′-(3-pyridyl)-4,2′:6′,4″-terpyridine)(1)(P1) by solvothermal method. Its crystal structure was determined with single-crystal X-ray diffraction (SC-XRD) techniques. The final composite Pd-NPs@1 catalyst was synthesized by a reduction method. The catalyst showed high catalytic performance and high recycling stability for nitrophenol degradation and cinnamaldehyde hydrogenation reaction.
