Abstract
This invention relates to a composition, comprising a carbon nanostructure having a palladium crystallite encapsulated therein; and more particularly, to worm-like carbon nanostructures attached to a carbon cluster, the worm-like nanostructures being comprised of a plurality of connecting sections of carbon tubes terminating in an end portion which encapsulates a palladium crystallite within its internal cavity.
Claims10
A composition comprising at least one worm shaped carbon nanostructure, said worm shaped carbon nanostructure comprising a plurality of connecting carbon sections terminating in an end portion, each section having a cone-shaped internal cavity, said end portion having an internal cavity with a palladium crystallite encapsulated therein.
A composition comprising a carbon nanotube having an internal cavity with a palladium crystallite encapsulated therein.
A composition comprising concentric polyhedra of carbon having an internal cavity with a palladium crystallite encapsulated therein.
A composition comprising a worm shaped structure having a palladium crystallite encapsulated therein, made by a process comprising the steps of:
- (a) passing a electric current through a positive and negative electrode, said negative electrode comprising a first carbon rod and said positive electrode comprising a second carbon rod, said second carbon rod having a hole therein filled with PdO paste;
- (b) vaporizing the PdO-filled carbon rod;
- and
- (c) depositing the carbon nanostructure having a palladium crystallite encapsulated therein at a tip of the negative electrode.
