Amorphous Ni-B hollow spheres synthesized by controlled organization of Ni-B nanoparticles over PS beads via surface seeding/electroless plating

The synthesis of amorphous Ni-B hollow spheres, exhibiting superior catalytic properties in acetophenone hydrogenation compared to their nanoparticle form, has been achieved by a combination of polystyrene microsphere templating and electroless plating.
