| titleOfInvention | Preparation method of composite material, product and application thereof |
| abstract | The invention discloses a preparation method of a composite material, a product and application thereof, wherein a layer of SnS grows on the surface of a SnO2 nano material 2 The heterojunction is constructed on the layer, so that the gas-sensitive performance of the material can be improved; the freeze drying technique is adopted to treat the sample, thereby preventing SnS 2 The SnO is grown on the surface of a sample by ALD (atomic layer deposition) after being oxidized and a higher specific surface area can be maintained in the drying process 2 The layer can prevent SnS in use 2 And a multi-layer heterojunction structure is formed, which is beneficial to further improving the long-term stability and sensitivity of the material. The composite structure prepared by the method can effectively improve the defects of insufficient sensitivity and stability of a single material, and can reduce the working temperature of the material. SnO prepared by the invention 2 /SnS 2 /SnO 2 The nano material can be used in the fields of toxic gas detection, photocatalytic pollutant degradation and the like. |
