Water-dispersible and magnetically recoverable Fe3O4/Pd@nitrogen-doped carbon composite catalysts for the catalytic reduction of 4-nitrophenol

摘要

Water-dispersible and magnetically recoverable Fe3O4/Pd@nitrogen-doped carbon catalysts were prepared. The porous nitrogen-doped carbon shells facilitate to enhance the stability of Pd nanoparticles and the water-dispersibility. The catalysts have good catalytic activity for the reduction of 4-nitrophenol and its derivatives, and can be magnetically separated from the reaction solution.
