Magnetically separable Pd-0/Co3O4 nanocatalyst can readily be obtained by the reduction of palladium(II) cations impregnated on cobalt(II, III) oxide at room temperature. The obtained Pd-0/Co3O4 nanocatalyst with 0.25% wt. palladium loading has outstanding catalytic activity with a record turnover frequency of 3048 min(-1) in the releasing H-2 from the hydrolysis of ammonia borane at 25.0 degrees C. They also provide out-standing reusability even after the tenth run of the hydrolysis of ammonia borane at 25.0 degrees. The high activity and superb stability of magnetically isolable Pd-0/Co3O4 nanoparticles are attributed to the favor-able interaction of palladium with the surface of reducible cobalt oxide.
