Název v původním jazyce

Highly selective NOx chemiresistive sensor based on n-type tungsten oxide nanorods

Popis výsledku v původním jazyce

In this article, tungsten trioxide (WO3) nanorods were successfully synthesized by a hydrothermal method and used for the detection of NOx. X-ray diffraction analysis revealed the hexagonal phase of WO3. Field emission scanning electron microscopy and transmission electron microscopy showed WO3 nanorods with an average diameter of 200 nm. X-ray photoelectron spectroscopy analysis showed that the oxidation state of tungsten in WO3 was +6. The WO3 sensor exhibited high sensitivity for the detection of NOx (50 ppm) at 250degree celsius. The sensor showed good linearity from 10 to 50 ppm of NOx, with a sensing response of 8-84%. Even under a high humidity (83%) environment, the sensor detected 50 ppm of NOx. The sensor exhibited good selectivity towards NOx compared to other oxidizing and reducing gases. The sensor also showed excellent stability even after 4 weeks.
