Novel catalytic gas sensor has long‐life and low power consumption

Abstract

Describes a new catalytic gas sensor which claims high stability and low‐consumed power by using extra fine wires of precious metals and the addition of a support stabilizer and pore‐making agents. Outlines the experiment methods and materials used, the principles of detection and the performance of the catalytic elements. Concludes that with the addition of a support stabilizer which makes the specific surface of the support decrease slowly during use, and a pore‐making agent which can eliminate the effect of the internal diffusion on the sensor, the novel catalytic sensor can be widely applied to the detection of damp gas in coal mines and various combustible gases on the earth’s surfaces.
