Abstract

This paper reports on a new ozone gas sensor based on alpha-Ag2WO4 nanorod-like structures. Electrical resistance measurements proved the efficiency of alpha-Ag2WO4 nanorods, which rendered good sensitivity even for a low ozone concentration (80 ppb), a fast response and a short recovery time at 300 degrees C, demonstrating great potential for a variety of applications.
