Abstract

The disclosed subject matter is directed to a method for producing nanoparticles, as well as the nanoparticles produced by this method. In one embodiment, the nanoparticles produced by the disclosed method have a high defect density.

Claims (7)

1. A nanoparticle prepared by:

(a) combining a solution consisting of hexamethylenetetramine (HMT) with a solution comprising a noble metal support solution to form a preliminary aqueous solution;

(b) heating said preliminary aqueous solution;

(c) combining said preliminary aqueous solution with a palladium salt to form a combined aqueous solution; and

(d) mixing said combined aqueous solution to produce a nanoparticle.

2. The nanoparticle of claim 1 , wherein said preliminary aqueous solution is heated to between about 48° C. and about 85° C.

3. The nanoparticle of claim 1 , wherein said nanoparticle has a high defect density.
