Study Design and Development Gas Sensor Technology for Motor Vehicle Exhaust Emissions

Abstract:

Metal oxide-based gas sensors, have been used in the detection of gaseous pollutants emitted from motor vehicles, such as CO, SO₂, NH₃, NOx, hydrocarbons (HC) etc. However, the problems that up to now are still faced by the metal oxide-based sensors are reviews their low sensitivity, low selectivity and lack of stability. Therefore, it is difficult, to the make such an accurate metal oxide-based sensor and stable over a long period of time. In this short review, it will be described the state-of-the-art technology, design and fabrication methods and various techniques that can be applied to improve the performance of metal oxide-based sensors. Keywords: gaseous pollutants, the motor vehicle emission, gas sensors, metal oxide
