Abstract

In the present paper we report the growth of monometallic and multimetallic particles from the reduction of metal sols. In particular the Au and Au–Pd alloys are reported on this work. A number of techniques are applied to the characterization of the particles. It is shown that particles from few nanometers to 100 pm can be prepared with a number of shapes and morphologies. Particularly conspicuous are the shapes with a five–fold symmetry axis.
