- Abstract
- The relationship between the microstructure of the noble-metal nanoparticles and the electrical properties of metal-decorated graphene oxide (GO), which is associated with the interaction energy between the noble metals and GO and the oxidation ability of the metal nanoparticles, is investigated. The interaction between the noble metals and GO plays a significant role not only in the microstructure of each nanoparticle during the deposition, but also in terms of the electrical and catalytic properties for gas sensing and water reduction. This interaction also determines whether the metal nanoparticles will exhibit 2D or 3D growth during the metal decoration.
