Highly sensitive MXene-based SO2 sensor enhanced by modification of SnO2 at room temperature
High-performance and room-temperature gas sensors are ideal for industrial production and environmental detection. Enhancing gas-detection capability by the use of highly conductive MXene in conjunction with metal oxide materials is a potential approach. In this work, we have prepared a gas-sensing composite device based on SnO2/V2CTx nanocomposites, which can be used to detect the concentration of SO2 gas at room temperature (~ 20 ℃). This paper modified two-dimensional (2D) V2CTx MXene with SnO2 nanoparticles by electrostatic binding method to synthesize SnO2/V2CTx composite nanomaterials. The experimental results show that at room temperature, the addition of SnO2 nanoparticles can markedly improve the gas-sensing response (from 66 to 83%) characteristics of pure V2CTx to SO2. The gas sensitivity of SnO2/V2CTx MXene nanocomposites can reach 83%, and its response/recovery time is 98 s/81 s under 10 ppm SO2. The gas-sensing composite devices made of SnO2/V2CTx composite nanomaterials also show good selectivity and application prospects.
