Abstract
The present paper reports at first our recent research work directed to improving NO2 sensing properties of In2O3 sensors by controlling pore structure inside In2O3 particles by fully utilizing ultrasonic spray pyrolysis of its precursor solution containing a polymer template. Other research results to be pronounced are high CO sensing performance of two kinds of solid electrolyte gas sensors, potentiometric anion-conducting polymer and NASICON sensors. For both sensors, high CO response and CO selectivity against H2 at room temperature even in humid environment could be achieved by the compositional design of the sensing electrodes.
