H₂ Sensing Performance of TiO₂-Based Diode-Type Sensors

Abstract:

H2 sensing properties of anodic TiO2 films equipped with Pd or Pd-Pt alloy electrodes has been investigated in air and in N2 atmosphere at 250°C and room temperature. The use of a Pd-Pt alloy electrode and a Pt paste improved the magnitude of H2 response, response time, stability and pretreatment- and atmosphere-dependent response properties under humid environments.
