Nitrogen dioxide gas-sensing properties of hydrothermally synthesized WO₃ · nH₂O nanostructures.

ABSTRACT: Nitrogen dioxide (NO₂) has been identified as a serious air pollutant that threats to our environment, human life and world ecosystems. Therefore, detection of this air pollutant is crucial. Metal oxide semiconductor is one of the best approaches frequently used to detect NO₂ at relatively low temperatures. Hydrated tungsten trioxide (WO₃ · H₂O), an n-type semiconductor, is regarded to be a promising material for fabricating gas sensors, which are widely used in environmental and safety monitoring. In this work, WO₃ · nH₂O nanoparticles have been synthesized using a polyfunctional surfactant-mediated hydrothermal approach in the addition of H₂C₂O₄ and K₂SO₄ at a molar ra
