Abstract

Highly sensitive and selective H2S sensors are required for human health and environmental monitor-ing. However, the humidity in the real working environment always harms either the sensitivity or se-lectivity of the H2S sensors. Here we reported a significant amplified sensitivity towards H2S gas in-duced by the variation of humidity for a chemiresistive sensor, which is based on Ti3C2Tx MXene-conjugated polymer composite. The sensor also provides a unique selectivity to H2S with a negative response, while positive to water vapor and most of the other analytes.
