Hexagonal tungsten trioxide (h-WO3) nano-materials can be widely used in many fields of optics, electrics and chemistry. In this work, three types of h-WO3 (single crystal, polycrystal and hierarchical) nanoflake arrays (WNFs) are synthesized through a simple hydrothermal method. The morphologies, c...
