Preparation of Pt–Ru bimetallic catalyst supported on carbon nanotubes

[摘要] The template carbonization of polyphenyl acetylene yields hollow, uniform cylindrical carbon nanotubes with outer diameter almost equal to pore diameter of the template used. High resolution transmission electron microscopic investigation reveals that Pt–Ru nanoparticles are highly dispersed inside the tube with an average particle size of 1.7 nm.
