Rapid, solventless, bulk preparation of metal nanoparticle-decorated carbon nanotubes.

摘要: A rapid, solventless method is described for the decoration of carbon nanotubes with metal nanoparticles. The straightforward two-step process utilizes neither reducing agents nor electric current and involves dry mixing a precursor salt (e.g., acetate) (single- or multi-walled) followed by heating in an inert atmosphere. procedure scalable to multigram quantities generally applicable various other substrates nanofiber, expanded graphite, black) many salts Ag, Au, Co, Ni, Pd acetates). As model system, Ag nanoparticle-decorated nanotube samples were prepared under techniques, loading levels, thermal treatment temperatures, oxidative acid treatments. These nanohybrids characterized variety microscopic spectroscopic techniques. For example, X-ray diffraction scanning electron microscopy indicated that average size nanopart...
