Abstract

Ethanol sensing has important applications, including breath alcohol checkers. A highly selective and stable ethanol sensor—see Figure—based on single-crystalline divanadium pentoxide nanobelts is described, representing a new strategy for the design of novel practicable gas sensors. Potential problems caused by changes of relative humidity or the presence of other gases are ruled out.
