Fabrication of nanoparticles on vertically aligned multi-wall carbon nanotubes by e-beam evaporation

A novel composite electrode containing gold/platinum nanoparticles on the vertically aligned multi-wall nanotubes (MWCNTs) by electron beam evaporation (e-beam evaporation) is reported herein. The size of gold/platinum nanoparticles by e-beam evaporation was less than 10 nm, and distributed uniformly on the surface of vertically aligned MWCNTs. This straightforward process can fabricate high specific surface areas of gold/platinum nanoparticles on the MWCNTs, enhance the efficiency of organic fuel decomposition, and advance the sensor precision. In addition, the nanoparticles on the MWCNTs can also facilitate high electron mobility and chemical stability.
