Uniform carbon and carbon/cobalt nanostructures by solid-state thermolysis of polyphenylene dendrimer/cobalt complexes

Uniform carbon/Co nanorods with unique cross-sections (see Figure), Co/carbon core/shell nanospheres, and multiwalled carbon nanotubes are selectively prepared in high yield by solid-state thermolysis of polyphenylene dendrimer/cobalt complexes under controlled heating procedures. The obtained materials have potential catalytic and magnetic applications.
