Temperature dependent selective detection of ethanol and methanol using MoS2/TiO2 composite

Volatile organic compounds may cause blindness, organ failure and serve as tracer for air quality controls or environmental monitoring. However, their detection at lower concentration and discrimination between compounds belonging to the same class has remained a challenging task. Methanol and ethanol, for instance, are difficult to distinguish from each other using chemiresistive sensors. Here, we report a highly sensitive, and stable sensor...
