High-performance ethanol gas sensor achieved by assembling In2O3-modified ZnO on multilayered Ti3C2Tx MXene
A novel gas-sensing material is reported by assembling In2O3-modified ZnO on multilayered Ti3C2Tx MXene with a high specific surface area (160.88 m2g−1). The maximum response value (88.90) was achieved for 250 ppm ethanol at a low temperature of 150 °C, with a fast response/recovery time of 5.5/26 s. The detection limit reached 0.5 ppm with a response value as high as 1.45. This sensor also exhibited superior selectivity, reproducibility, and long-term stability. The results showed that the incorporation of In2O3 effectively reduced the operating temperature of the ZnO sensor, and the MXene composite significantly enhanced the response value and reduced the response/recovery time. The enhanced gas-sensing performance was mainly attributed to the high specific surface area and three-dimensional hybrid heterostructure. This paper provided valuable insights on the modification of ZnO-based sensing materials.
