The Pd-B/g-Al2O3 amorphous alloy catalyst and Pd/g-Al2O3 crystalline metal catalyst were prepared by KBH4 reduction and routine impregnation, respectively. Pd-B/g-Al2O3 and Pd/g-Al2O3 catalysts were characterized by XRD and SEM. It was found that the catalytic activity of the Pd-B/g-Al2O3 amorphous alloy catalyst was higher than that of the Pd/g-Al2O3 crystalline metal catalyst in the anthraquinone hydrogenation.
