Metal Oxide Gas Sensors: Sensitivity and Influencing Factors

· High surface areas make them excellent supporting materials, which can obtain well-dispersed gas sensor materials or catalysts. Figure 11 shows the sensitivities of SnO 2 (40 wt%) /SBA-15 composite sensor and pure SnO 2 sensor to 1,000 ppm of H 2 . The SnO 2 (40 wt%)/ SBA-15 sensor displays a much enhancement of sensitivity to H 2, especially at 250 °C where the sensitivity of the sensor …

Gas Sensor - an overview | ScienceDirect Topics

Gas sensors are generally understood as providing a measurement of the concentration of some analyte of interest, such as CO, CO 2, NO x, SO 2, without at this point dwelling on the plethora of underlying approaches such as optical absorption, electrical conductivity, electrochemical (EC), and catalytic bead (see Section 3). However, and as discussed in Section 2, many other gas sensors ...
