A novel CdO:In2O3nano composite has been synthesized by a pyrolysis method. The prepared nano composites have been carefully characterized using X ray diffraction and atomic force microscopy. The obtained results showed that the synthesized nano compositeCdo:In2O3 at optimum conditions has excellent grains. It was found that synthesized CdO:In2O¬3nano composite can be used as NO2 gas sensing to exhibit the highest sensitivity for NO2 at 200°C. The constructed sensor showed a very low detection limit of 5 ppm .
