A sensor and a sensing method for use in a gas or gaseous mixture is provided. The sensor (9) includes a gas sensitive material (4), MO3-x, in which M is predominantely or exclusively Mo; and MO3-x is a substoichiometric molybdenum trioxide which exhibits a response in the form of an increase or a decrease in an electrical property of the material in the presence of a gas. This electrical property is measured by an electrical measuring means (6). The gas sensitive material (4) is in direct communication with two electrodes (2, 3) mounted to the gas sensitive material (4) and arranged for contact with a gas or gaseous mixture. |
