RADIAL SINGLE-WALL CARBON TUBES GROWING ON SURFACES OF PD PARTICLES

Palladium (Pd) particles protruding single-wall (SW) carbon tubes were produced by are evaporation of Pd-graphite composites in helium gas. Transmission electron microscopy revealed radial and dense SW tubes gr owing from a Pd particle in the metallic fee phase. The length and the diameter of SW tubes were typically 40 nm and 1.5 nm, respectively. A naked Pd particle with a tail of filamentous carbon, showing 'tadpole ' type morphology, was also described.
