Title:
NOBLE METAL CATALYST AND CONSTANT POTENTIAL ELECTROLYTE GAS SENSOR
Document Type and Number:
WIPO Patent Application WO/2014/203923
Kind Code:
A1
Abstract:
A noble metal catalyst causing metal nanoparticles to be supported on carbon particles acting as a carrier, said metal nanoparticles having an average particle diameter of no more than the average particle diameter of the carbon particles. The noble metal catalyst is used for each electrode in a constant potential electrolyte gas sensor (X) comprising: a working electrode (11), as a gas electrode that detects gas, that causes detected gas to chemically react; a counter electrode (12) for the working electrode (11); and a reference electrode (13) controlling the potential of the working electrode. Said electrodes face an electrolyte housing section (31) of an electrolytic cell (30) housing electrolyte (20).
