The detection of hydrogen sulfide (H2S) in exhaled breath at room temperature is essential for health monitoring and disease diagnosis. This study investigates a ZnO/Ti3C2TX nanocomposite synthesized by combining ZnO nanoparticles, prepared hydrothermal method, with Ti3C2TX MXene. Experimental results demonstrate that the sensors exhibit excellent H2S performance high sensitivity, rapid response time, robust recovery capability. Specifically, ZnO/Ti3C2TX-1.0 wt % sensor shows 85.116 5 ppm H2S, which 14-fold 35-fold greater than pure MXene, respectively. exhibits (50 s) time (115 100 ppb H2S. Additionally, it exceptional sensitivity to low concentrations, limit as 1 ppb. Based on sensing performance, oral gas demonstrates effectively differentiates levels healthy patient samples. These findings highlight potential temperature, offering new insights developing ultrasensitive biogas sensors.
