Highly stable hydrogen sensing properties of Pt–ZnO nanoparticle layers deposited on an alumina substrate for high-temperature industrial applications

Redispersing Ir Nanoparticles via a Carbon-Assisted Pyrolysis Process to Break the Activity–Stability Trade-Off of H2 Sensors

“…The Ir red /ZnO-450 sensor exhibits a wide detection range of H 2 concentrations (10–2000 ppm), fast response speed, and a higher response (2.79@500 ppm) with a lower OWT value (265 °C). The specific comparison values of the above performance are summarized in Table S1. − …”
