- •
3D hierarchical niobic acid microflower was synthesized by a surfactant-free method.
- •
The microflower was composed of ultrathin nanosheets with ∼5 nm thickness.
- •
The microflower showed high photoactivity owing to the 3D structural features.
- •
This microflower was converted to Nb2O5 without significant structural alteration.
- •
Nb2O5 nanoneedles can also be obtained by adjusting the pH value during synthesis.
