Sensitivity and Selectivity of SnO2-Based Sensor for CO and H2 Detections: A Novel Method to Detect Simultaneously the CO and H2 Concentrations

Abstract:

SnO2-based sensor has many advantages such as low cost, small size, high reliability, and long operating life, but selectivity has been a major obstacle on the application for discriminating gas species in mixture of multi-reduction gases. To resolve the problem in this work, the pure SnO2 and NiO-, CuO- and Pt-modifying SnO2 as sensing materials were prepared by sol-gel method, the sensor cells were fabricated and characteristics of sensitivity and selectivity of the sensor cells to CO and H2 at 400°C were investigated. The results showed that the response of CO was improved obviously by doping 20mol%NiO or 5mol%CuO into the SnO2, while the response of H2 was changed no more, and the responses of CO and H2 both were enhanced dramatically by bearing 1mol%Pt into the SnO2. On the basis of empirical equation (R=1+kCn), two sensor cells with different selectivity were introduced to assemble a novel SnO2-based sensor, and proposed a potential method to detect the concentrations of CO and H2 in multi-component gases, in which the parameters of k and n for sensor cells were obtained and feasibility of the method was demonstrated.
