One-step seeding growth of magnetically recyclable AU@Co core-shell nanoparticles: Highly efficient catalyst for hydrolytic dehydrogenation of ammonia borane

Article abstract of DOI:10.1021/ja910513h

Magnetically recyclable Au@Co core?shell nanoparticles were successfully synthesized in a one-step seeding-growth process within a few minutes. They were thermally stable and exhibited higher catalytic activity toward the dehydrogenation of ammonia borane than Au?Co alloy and the pure metal counterparts. This is a large enhancement in the catalytic activity of core?shell structured nanoparticles and will provide a new design principle for heterogeneous catalysis.
