Specifically exposed planes could play a crucial role in the chemical activity of nanomaterials. The morphology and structure of nano-structured WO3 particles with {020} exposure planes were successfully controlled via hydrothermal synthesis technology by adjusting the synthesis temperature and time. Additionally, the gas-sensing properties of sensors fabricated using these WO3 particles were investigated to detect different volatile gases. All the samples were found to be sensitive to alcohol gas, and the WO3 nanoparticles synthesized at 150 °...
