Abstract

We develop the sculpting method to synthesize well-defined nanocrater catalysts with the hollow core/metal shell structure within an array via chemical and plasma processes. Also, we successfully demonstrate that unique morphologies of nanocrater catalysts as effective templates allow the exclusive control of the number of walls and outer diameters in carbon nanotubes.
