Abstract

Co–Co2B and Ni–Ni3B nanocomposites were synthesized by the reduction of Co2+ and Ni2+ ions using ammonia–borane in methanol. The Co–Ni–B nanocomposite was synthesized by the co-reduction of Co2+ and Ni2+ ions. The catalytic activities of these metal nanocomposites were studied for the dehydrogenation of ammonia–borane in methanol. Three moles of H2 were liberated in 2.5 min and 4.2 min in case of Co–Co2B and Ni–Ni3B nanocomposites, respectively (catalyst/AB = 0.2). The Co–Ni–B nanocomposite showed greater activity compared to individual metal–metal boride nanocomposites: 3 moles of H2 were liberated in 1.5 min (catalyst/AB = 0.2). The catalysts were highly recyclable and the activities remained almost unchanged even after several cycles.
