Reactivity of Metallic Nanoparticles Depends on Aspect Ratio

Reactivity of Metallic Nanoparticles Depends on Aspect Ratio 

The reaction of cyanide with gold, in the presence of air and water, produces the gold-cyanide complex ion [63]  

This reaction is the industrially important cyanide process for recovering gold from rocks [63] in that case, elemental gold is predpitated out by adding Zn dust to reduce the Au(I) back to Au(0).
