What is the response time and recovery time of the MoSe2/TiO2 composite sensor for NH3 and DMF?

Label:chem

Topic
Response and recovery times are important parameters for evaluating the practical usability of gas sensors. These times indicate how quickly the sensor can detect and recover from the presence of target gases.

From: "MoSe2-based room temperature gas sensor with a sub-parts-per-billion limit for ammonia and N,N-dimethylformamide", Mater. Adv., 2025,6, 2854-2866
Answer
For NH3, the response time is 150 seconds under both 40% and 80% relative humidity, while the recovery times are 37 seconds at 40% RH and 110 seconds at 80% RH. For DMF, the response times are 160 seconds at 40% RH and 150 seconds at 80% RH, with recovery times of 74 seconds and 45 seconds, respectively.
