Highly Selective CO Sensor Using Indium Oxide Doubly Promoted by Cobalt Oxide and Gold
Source abstract
Abstract
Among the ‐based elements loaded with each of 12 metal oxides [0.5 weight percent (w/o) each], the ‐added element was outstanding in sensitivity and selectiveness to CO at 250°C. Remarkably the sensing properties of this element could be increased further by the addition of Au (0.04 w/o). The element thus obtained, Au (0.04 w/o)‐Co (0.5 w/o)‐ , gave excellent characteristics in sensitivity to CO, selectivity to CO against and other selected gases, and responses rate at 250°C, giving promise of being applied as a CO sensor for safety control of gas appliances.
