Abstract

A catalytic nanotemplate including a freestanding template particle and a director associated with the surface of the freestanding template particle. The free standing template particle may have multiple segments and the director may be associated with one or more of the segments. In instances where multiple segments are present, the segments may be made of different materials or be of the same material in different forms. More than one type of director or no director may be associated with any particular segment.

Claims (11)

1. A method of synthesizing a nanoparticle comprising:

providing a freestanding template particle;

associating a director with a surface of the freestanding template particle;

selectively forming a nanoparticle on the director; and

releasing the nanoparticle from the director and freestanding template particle without consuming the freestanding template particle.

2. The method of claim 1 wherein the releasing step comprises completely removing the director.

3. The method of claim 2 further comprising:

recovering the freestanding template particle;

re-associating the freestanding template particle with the director.

4. The method of claim 1 wherein the releasing step comprises removal of the nanoparticle from the director and freestanding template particle without substantially removing the director.

5. The method of claim 4 comprising recovering the freestanding template particle and director association.
