Experimental study demonstrates direct synthesis of oxidation-resistant nickel catalysts on silica-coated magnetite, suggesting broad utility across industrial heterogeneous catalysis.

Key Points

To synthesize a highly active, oxidation-resistant nickel catalyst using an organometallic precursor to eliminate challenging high-temperature activation steps.
Decomposed the organometallic precursor bis(1,5-cyclooctadiene)nickel(0), Ni(COD)2, onto silica-coated magnetite (Fe3O4@SiO2) supports under controlled conditions.
Assessed catalytic activity and in situ regeneration via cyclohexene hydrogenation under mild conditions after air exposure.
Produced catalysts predominantly composed of active Ni(0) that resist severe oxidative deactivation.
Demonstrated that surface oxide species formed from air exposure reduce in situ under mild hydrogenation conditions, completely restoring baseline catalytic activity.
