Abstract

PURPOSE: To provide a highly sensitive methane gas detector by adding and mixing a cocatalyst to and with refractory insulating oxide (aggregate), and then mixing the mixture with semiconductor to thereby enable to increase largely the cocatalyst amount to the mixture without deteriorating the detector.
CONSTITUTION: A mixture obtained by adding cocatalyst such as, for example, Pt, Pd, Ir, etc. to refractory insulating oxide such as, for example, Al2O3, SiO2, etc. is mixed with n-type metal oxide semiconductor of SnO2 ZnO, In2O3, etc. at approx. 1:1 by weight. The mixture is kneaded with water, and formed in predetermined shape to thereby provide a methane gas detector. When the cocatalyst is added to the refractory insulating oxide, Al2O3 is dipped in the ethanol solution of, for example, H3PtCl6, is then dried, and then pyrolytically decomposed with H3PtCl6 adhered at approx. 400°C in hydrogen gas stream. This is thus reduced to metal. The preferable amount of the cocatalyst to be used is approx. 0.01W3wt% with respect to the semiconductor.
