<abstract xmlns="http://www.w3.org/1999/xhtml">SmCoO3 gas sensor has been developed with high sensitivity for CO2 gas by doping Ba. Nanostructured SmCoO3 and Sm1-xBaxCoO3 (x = 0, 0.1, 0.15, 0.2) were obtained by EDTA-Glycol method. The operation temperature falls and sensitivity increases from 425 to 370°C when Ba concentration in SmCoO3 changes from x = 0 to x = 0.1. Ag impregnation over Sm0.9Ba0.1CoO3 sensor, on exposure to CO2 at about 360°C showed an increased sensitivity as well as the response time also decreases. The possible CO2 sensing mechanism is proposed on the basis of available literatures.</abstract>
