Abstract
Abstract
In this paper, research on a CO catalytic gas sensor based on nano-crystalline perovskite oxide NdFeO
3 designed for exhaust gas measurement is presented. Nano-crystalline oxide NdFeO
3 was synthesized by a sol–gel citrate technique. The gas sensing characteristics of this sensor were investigated in the concentration range of CO between 0 and 5 vol.% in air. The influences of C
