The crystal structure of WO3 is orderly arranged with WO6 structure, possessing crystal channels for convenient charge transfer and ion diffusion. Using effective strategies to broaden the crystal channels of this materials can improve the charge transfer and ion diffusion. In this work, we have facilely utilized a sample hydrogenation method to introduce distorted WO6 structures into the crystal of tungsten oxide, which leads to the crystal reconstruction and W5O14 formation with large crystal channels. Due to the existence of large crystal channels, as-fabricated W5O14 nanosheet arrays achie...
