Development of a dry process for coating metal nanoparticles on carbon nanotubes

Metal nanoparticles such as platinum (Pt) and gold (Au) decorated CNTs have been thoroughly investigated as electrode of fuel cells and chemical and biological sensors. In these applications, the size and the density of nanoparticles are very important, because the catalyst activation depends on the...
