Magnetically recoverable Fe3O4/CoPd/NC nanocatalyst for high-performance Suzuki-Miyaura cross-coupling reactions

Abstract

A magnetically recoverable Fe3O4/CoPd/NC nanocatalyst was synthesized via controlled pyrolysis of a Pd-loaded ZIF-67 precursor. Characterization confirmed the formation of bimetallic CoPd nanoparticles (~ 3.5 nm) embedded in a nitrogen-doped carbon matrix. The catalyst showed high efficiency in Suzuki–Miyaura coupling, yielding 78% under mild conditions (60 °C, EtOH/H2O). The superior activity stems from the electronic synergy between Co and Pd. This system offers rapid magnetic separation and excellent reusability, providing a sustainable solution for bimetallic heterogeneous catalysis.
