| Abstract: | The nanocrystalline In 2O 3 powder was prepared by sol-gel method and its construction was expressed by XRD (X-Ray Diffraction) and SEM (Sweep Electron Microscope) view. The sintering-type gas sensor based on this material has excellent sensing properties to CO gas. The sensitivity, selectivity and the rates response and recovery were improved greatly by addition of Co 3O 4 and Au. |
