Abstract
Nickel nanoparticles stabilised by Fe3O4-Lignin a core-shell (Fe3O4-Lignin@Ni-NPs) were synthesised in water. Different methods have been used to characterise the Fe3O4-Lignin@Ni-NPs, including UV-Visble and fourier transform infrared (FT-IR)spectroscopy, energy dispersive X-ray (EDX) spectra, powder X-ray diffraction (PXRD), scanning electron microscopy (SEM)and tunnelling electron microscopy. (TEM). Ni-NPs as prepared to have an average size of about 15 nm, which was consistent with the size predicted by PXRD. As the corresponding alcohol products were obtained in good to outstanding yields of up to 99% in quick reaction times of 1.25 to 3.0 h, this heterogeneous and magnetically recoverable catalyst has shown promising activity in the transfer hydrogenation of carbonyl compounds. Additionally, the catalyst could be readily recovered using an external magnet by filtration and repurposed up to six times with continued catalytic activity.
