| Abstract: | The oxide based semiconductor sensors have been widely used for the detection of toxic, hazardous gases. ZnO is an important semiconductor gas sensing material, especially nano-ZnO is one of the most widely studied gas sensitive materials because of the small particle size and large specific surface area.The gas sensing mechanism and main characteristics of the ZnO gas sensor is simply introduced, and the research progress on the improvement of the nano-ZnO gas sensing properties through the preparation of specific morphology and nano structure is reviewed, and the addition of various elements is reviewed. In the end, the existing problems and the future development for nano-ZnO gas sensor are further summarized. |
