Claims15
A ring-shaped nanostructure comprising first metal atoms and second metal atoms,
- wherein the first metal atoms comprise copper,
- wherein the second metal atoms are selected from the group consisting of gold, platinum, palladium, and combinations thereof.
A ring-shaped nanostructure obtained by a method comprising:
- providing a first metal nanosheet having first metal atoms, wherein the first metal atoms comprise copper, and
- performing a synthetic strategy, the synthetic strategy comprising:
- replacing a portion of the first metal atoms with a corresponding number of second metal ions, and
- promoting first metal atom diffusion to provide the ring-shaped nanostructure.
A hollow nanotube comprising first metal atoms and second metal atoms, wherein the first metal atoms are copper and the second metal atoms are gold, and wherein the first metal atoms and the second metal atoms are homogenously distributed throughout the hollow nanotube.
