Sensing Properties of Diode-Type Gas Sensors

Article Preview

Abstract:

Several approaches to improve H2 sensing properties of TiO2-based diode-types sensors have been investigated. Those include the adoption of a Pd-Pt alloy electrode instead of using a pure Pd electrode, formation of a polymer coating atop the Pd-Pt alloy electrode and an Au coating on the Pd-Pt alloy electrode. The advantages of the using of the Pd-Pt alloy electrode, the polymer or Au coatings are demonstrated.
