A novel magnetically recoverable copper complex catalyst based on Fe3O4 nanoparticles as a magnetic carrier was successfully synthesized. The catalyst was characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared (FTIR) spectroscopy, and alternating gradient magnetometry (AGM). The Henry reaction catalyzed by this prepared magnetically recoverable copper complex catalyst proceeded in high yield (97 %) and with high conversion (94 %). The prepared catalyst possesses superparamagnetic properties and can be recycled very conveniently using an external magnetic field. The self-prepared catalyst has excellent catalytic selectivity and good reusability, making this method a clean and energy-efficient process.
