Ag nanoparticles were prepared on the surface of multi-walled carbon nanotubes (MCNTs) by thermal evaporation deposition at room temperature. The morphology and microstructures of Ag/CNTs composites were characterized by SEM, XRD, TEM and HRTEM. The measurement results verify the nanocrystal shape of Ag nanoparticles on the MCNTs. Ag nanoparticles are distributed evenly on the MCNTs and the density of Ag nanoparticles reaches 1011 cm-2.Ag nanoparticles present round or elliptical patterns and the round particles have larger diameter than the elliptical ones. The MCNTs are deformed at where Ag nanoparticles grow, which should be attributed to the interaction between Ag nanoparticles and MCNTs during the evolution. The heterojuntion materials are formed by the deformed MCNTs and as-grown Ag nanoparticles. It is found that the heterojuntion materials share mutual connections and constitute a net structure because the chemical bonds between Ag nanoparticles and MCNTs have fixation on reciprocal chiasmata MCNTs. The as-prepared 0-1 dimensional materials have promising applications in sensors, catalysis and optoelectronic devices.
