Nickel boride (Ni2B) is known to be an excellent catalyst for hydrogenation of olefin structures under mild reaction conditions. Its susceptibility oxidation in air environments, however, limits its practical applications. Here, a hydrazine-passivated nickel boride/nickel (NiBx/Ni) heterostructured developed address the problem while improving conversion efficiency styrene ethylbenzene real polystyrene (PS) pyrolysis oil. The calculated turnover frequency 24.9 mmol/h·g, with 99.9% selectivity, representing 38.3% improvement compared control Ni2B (18.0 mmol/h·g). This outstanding performance attributed increased charge density on both Ni and B, induced by strong hydrazine reductant, which surpasses other amine-structured ligands, such as ethanolamine ethylamine. Additionally, enhanced magnetic properties NiBx/Ni, resulting from Ni(111) nanocrystalline structure along easy axis magnetization, enable facile recovery after neodymium magnet. demonstrated stability, retaining catalytic efficacy over five consecutive cycles only 4% loss activity. study highlights potential NiBx/Ni low-cost efficient industrial
