SnO₂–TiO₂ composite materials were synthesized and investigated for their potential application in CO₂ gas sensing. The structural and electrical properties of the prepared composite were studied to evaluate its sensing characteristics. Incorporation of TiO₂ into SnO₂ modified the electrical conductivity and surface interaction with CO₂ molecules, influencing sensor response. The results demonstrate that the SnO₂–TiO₂ composite exhibits promising characteristics for developing sensitive, stable, and efficient CO₂ gas sensors. P4(40SnO₂:60TiO₂) sensor exhibited the highest sensitivity of approximately 1.33 at 2500 ppm CO₂.
