Controlled synthesis of monodisperse WO3·H2O square nanoplates and their gas sensing properties

- Monodisperse WO3·H2O square nanoplates were controlled hydrothermal synthesized.
- The thickness of the nanoplates increases due to the prolongation of reaction time.
- The special kind of nanoplates show excellent C2H5OH gas sensing.
- The gas sensing can be influenced by the crystal facet percentage in nanoplates.
