Mixtures of ITO and SnO2 powders were prepared by a solid-state reaction method in order to produce porous composite materials. X-ray diffraction, scanning electron microscope and gas sensing testing system have been used to analyze the microstructure and properties of it .It has been concluded that when the sintering temperature is 1573K,it has better gas-sensing properties. The pore structure and CO gas sensing property of porous SnO2-In2O3 composite materials can be improved with the increase of SnO2 contents.
