As a common environmental pollutant and an important breath biomarker for several diseases, it is essential to develop hydrogen sulfide gas sensor with low-ppb level detection limit prevent harmful exposure allow early diagnoses of diseases in low-resource settings. Gold doped/decorated tungsten trioxide (Au-WO3) nanofibers various compositions crystallinities were synthesized optimize H2S-sensing performance. Systematically experimental results demonstrated the ability detect 1 ppb H2S response value (Rair/Rgas) 2.01 using 5 at % Au-WO3 average grain sizes around 15 nm. Additionally, energy barrier difference sensing materials air nitrogen (ΔEb) power law exponent (n) determined be 0.36 eV 0.7, respectively, 450 °C indicating that O– predominately ionic oxygen species adsorption significantly altered Schottky between grain. Such quantitative analysis provides comprehensive understanding mechanism.

Highly efficient gas sensors able to detect and identify hazardous gases are crucial for numerous applications. Array of conventional single-output is currently limited by problems including drift, large size, high cost. Here, we report a sensor with multiple chemiresistive potentiometric outputs discriminative detection. Such applicable wide range semiconducting electrodes solid electrolytes, which allows tailor optimize the sensing pattern tuning material combination conditions. The performance boosted equipping mixed-conducting perovskite electrode reverse polarity. A conceptual dual sensitive achieves superior three-dimensional (sub)ppm discrimination humidity seven (2-Ethylhexanol, ethanol, acetone, toluene, ammonia, carbon monoxide, nitrogen dioxide), enables accurate early warning fire hazards. Our findings offer possibilities design simple, compact, inexpensive, highly multivariate sensors.
