electrochemical characterization on RuO_2 centre dot xH_2O/carbon nanotubes composite electrodes for high eneryg density supercapacitors

摘要

Carbon nanotubes(CNTs) are among the most promising nanomaterials that have been discovered,with potential applications as nanodevices,field emission displays and energy storage devices 1-4.Hollow,open-ended,well-ordered CNTs are,however,required for these applications.
