Abstract
A Pd-Pt bi-metal micro catalytic methane sensor, with loading quantity and molar ratio optimized by inkjet printing technique, was proposed for the first time. Catalytic support was precisely patterned by screen printing a porous alumina support. To optimize the sensor's performance, relation between catalyst loading quantity and power consumption of the sensor was investigated, as well as that between the Pd-Pt molar ratio and sensitivity. At working temperature of 450°C, sensor's sensitivity and power consumption can reach 12.0 mV/%CH4 and 300 mW with molar ratio of 9:1.
