A photoresponsive inorganic microfiber with a plasmonic core–shell structure responds to visible light to achieve self-protection against oxidation in an open environment. The microfibers are synthesized via a newly developed reagent-free electrolytic method and have unique interfacial structures and high surface activity.
- Antioxidation self-protection
- Core–shell nanostructures
