Structure Engineering of Ni/SiO₂ Vegetable Oil Hydrogenation Catalyst via CeO₂.

ABSTRACT: Inspired by our finding that metallic Ni particles could be uniformly distributed on a reduced CeO₂ surface and stabilized on Ce³⁺ sites, we suppose a possible improvement in the activity and selectivity of the MgNi/SiO₂ vegetable oil hydrogenation catalyst by increasing the surface metal Ni availability via modification by ceria. The proposed approach involved the addition of a CeO₂ modifier to the SiO₂ carrier and as a catalyst component. Evaluation of the structure, reducibility, and surface and electronic states of the CeO₂-doped MgNi/SiO₂ catalyst was performed by means of the Powder X-ray diffraction (PXRD), Scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), and X-ray photoelectron spectr
