| description | Real-time sensing of hydrogen sulfide (H<sub>2</sub>S) at room temperature is important to ensure the safety of humans and the environment. Four kinds of different nanocomposites, such as MXene Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>, Ti<sub>3</sub>AlC<sub>2</sub>, WS<sub>2</sub>, and MoSe<sub>2</sub>/NiCo<sub>2</sub>O<sub>4</sub>, were synthesized using the hydrothermal method in this paper. Initially, the intrinsic properties of the synthesized nanocomposites were studied using different techniques. P-type butane and H<sub>2</sub>S-sensing behaviors of nanocomposites were performed and analyzed deeply. Four sensor sheets were fabricated using a spin-coating method. The gas sensor was distinctly part of the chemiresistor class. The MXene Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>/NiCo<sub>2</sub>O<sub>4</sub>-based gas sensor detected the highest response (16) toward 10 ppm H<sub>2</sub>S at room temperature. In comparison, the sensor detected the highest response (9.8) toward 4000 ppm butane at 90 °C compared with the other three fabricated sensors (Ti<sub>3</sub>AlC<sub>2</sub>, WS<sub>2</sub>, and MoSe<sub>2</sub>/NiCo<sub>2</sub>O<sub>4</sub>). The MXene Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>/NiCo<sub>2</sub>O<sub>4</sub> sensor showed excellent responses, minimum limits of detection (0.1 ppm H<sub>2</sub>S and 5 ppm butane), long-term stability, and good reproducibility compared with the other fabricated sensors. The highest sensing properties toward H<sub>2</sub>S and butane were accredited to p–p heterojunctions, higher BET surface areas, increased oxygen species, etc. These simply synthesized nanocomposites and fabricated sensors present a novel method for tracing H<sub>2</sub>S and butane at the lowest concentration to prevent different gas-exposure-related diseases. |
