But, a non-spherical particle would have greater surface area. I think I read that the sphere is the most efficient in surface to volume ratio; so, an irregular surface would be better. I think that is why Raney Ni is so reactive. The surface is NOT a sphere. The best nanoparticle would be constructed by a vacated process like Raney or some type explosive destruction process. The more irregular the surface, the better. T
