Fabrication of Au nanoparticles supported on CoFe2O4 nanotubes by polyaniline assisted self-assembly strategy and their magnetically recoverable catalytic properties

Au nanoparticles supported on the core-sheath CoFe2O4/PANI nanotubes as an efficient magnetically recoverable nanocatalyst exhibited good catalytic activity and reusability for the hydrogenation of 4-nitrophenol.
