説明
Abstract Skeletal Ni catalysts were prepared from an amorphous Ni 40 Zr 60 alloy (a-NiZr) by the selective extraction of Zr moieties by the HF treatment, followed by heating at various temperatures under vacuum, oxygen and hydrogen atmosphere. The HF treatment selectively extracted Zr moieties from a-NiZr, which resulted in the formation of high-surface-area and skeletal Ni metals. The oxygen treatment at 423 K and following hydrogen treatment at 473 K enhanced the catalytic activities of the skeletal Ni catalyst in the hydrogenation reaction of 1-octene with molecular H 2 . The temperatures and atmosphere of the pretreatment strongly affected to the catalytic performances of the skeletal Ni catalysts.
