Core-shell-structured carbon nanofiber-titanate nanotubes with enhanced photocatalytic activity

- We synthesize the core-shell-structured carbon nanofiber-titanate nanotubes.
- Titanate nanotubes are formed during the alkaline hydrothermal treatment.
- Carbon nanofiber-titanate nanotubes show superior photocatalytic activity.
- The BET surface area was increased by the alkaline hydrothermal treatment.
