Nanoparticle-electrode impacts: the oxidation of copper nanoparticles has slow kinetics.

Abstract:

The electrochemical oxidation of copper nanoparticles in aqueous solution was studied via their electrolysis upon impacting a carbon electrode held at a suitable anodic potential. The oxidations were found to be quantitative such that complete oxidation of the particle took place allowing their sizing. Experiments were performed in 1.0 M HNO(3) and in 1.0 M HNO(3)-0.1 M KCl. In the former case a two electron oxidation to Cu(2+) was seen at a formal potential of +0.11 V (vs. SCE). In the latte...
