Abstract
This paper reports a new strategy for nanoparticle surface assembly so that they form anisotropic fibril-like features, consisting of particles directly attached to each other, which can extend 500nm from the surface. The particles are both formed and deposited in a single step process enabled via the use of a pulsed plasma based technique. Using this approach, we have successfully modified zinc oxide rods, up to several hundred nanometers in diameter, with 25nm diameter copper nanoparticles for catalytic applications. The resulting structure could be modelled using a diffusion limited aggregation based approach. This gives the material the appearance of marine coral, hence the term nanocoral.
