- •
In4Sn3O12–TeO2 composite nanoparticles were synthesized via a facile hydrothermal route.
- •
The response of the In4Sn3O12–TeO2 composite sensor to CO was stronger than the pristine In4Sn3O12 sensor.
- •
The response of the In4Sn3O12–TeO2 composite sensor to CO was faster than the pristine In4Sn3O12 sensor.
- •
The improved sensing performance of the In4Sn3O12–TeO2 nanocomposite sensor is discussed in detail.
- •
The In4Sn3O12-based nanoparticle sensors showed selectivity to CO over NH3, HCHO and H2.
