In this report, CoFe 2 O 4 /Polypyrrole (PPy)/Pd ternary composite nanofibers are fabricated through a one‐step redox reaction between pyrrole and Na 2 PdCl 4 in the presence of electrospun CoFe 2 O 4 nanofibers in ethylene glycol (EG). The generation of Pd nanoparticles is accompanied by the formation of PPy on the surface of electrospun CoFe 2 O 4 nanofibers during the redox reaction. The as‐prepared CoFe 2 O 4 /PPy/Pd composite nanofibers may be used as efficient catalysts for the p ‐nitrophenol hydrogenation with an apparent rate constant ( k app ) of about 13.2 × 10 −3 s −1 . The CoFe 2 O 4 /PPy/Pd composite nanofibers show good magnetic properties, which can be readily recycled under an external magnetic field.
