Sensor for selectively and separately detecting carbon monoxide and/or methane in room air of the house

摘要

Sensor for detecting carbon monoxide and / or methane has a plate with an electrode structure and connecting electrodes and a gas-sensitive layer on the electrode structure. Sensor (1) has a plate (11) with an electrode structure (13) and connecting electrodes (14) and a gas-sensitive layer (112) on the electrode structure. A heating device (18) is also included with connecting electrodes (114). The gas-sensitive layer (112) consists of Ga2O3 thin layer (112) on the electrode structure with a thick porous Ga2O3 layer on the thin layer. Gold clusters (212) are inserted on and in the thin and thick layers. An Independent claim is also included for a process for detecting carbon monoxide and / or methane in air comprising using the above sensor by measuring sensitivity values at subsequent time intervals at the temperatures 650-800 deg C and 800-650 deg C
