HYDROGEN DETECTING MATERIAL AND ITS MANUFACTURING METHOD

Japanese Patent JP2007225299

A

To provide a hydrogen detecting material changed in its optical characteristics when exposed to an atmosphere containing a hydrogen gas, and its manufacturing method.

The hydrogen detecting material changed in its optical characteristics when exposed to the atmosphere containing the hydrogen gas and its manufacturing method are characterized in that (1) the main component of the hydrogen detecting material is palladium oxide (PdO) and the shape of the hydrogen detecting material is a thin film, (2) a catalytic metal layer is formed on the surface of the hydrogen detecting material, (3) either one of palladium (Pd), platinum (Pt) and gold (Au) is used in the catalytic metal layer and (4) the palladium oxide film is obtained by heat-treating palladium vapor-deposited on a transparent substrate comprising quartz glass or the like at 500-700°C in air or an oxygen atmosphere to form palladium oxide (PdO).
