The application of semiconductor nanoparticles to gas-sensitive materials is an emerging field of research, and the research progress on the ultra-fine processing of SnO2 semiconductors is reviewed. Various preparation methods were described in detail. Controlling the size of the material and the distribution of the particle size to ensure the stable existence of the nanoclusters is the key to preparing the nano-SnO2. The gas sensing properties of the nano-SnO2 semiconductor material are analyzed. Since the material ratio Surface area increases, active sites increased, and has excellent gas sensitivity; and prospects for its further development made.
