| titleOfInvention | Preparation method of tin dioxide gas-sensitive material with hierarchical structure for detecting formaldehyde gas |
| abstract | The invention provides a preparation method of a tin dioxide gas sensitive material with a hierarchical structure for detecting formaldehyde gas, which comprises the steps of weighing a tin source, adding the tin source into a container, adding a solvent and PVP (polyvinyl pyrrolidone) and stirring to enable the tin source to be a transparent viscous liquid; collecting transparent viscous liquid into an injector, putting the injector into an electrostatic spinning machine, and calcining the collected sample after spinning is finished to obtain the tin oxide hollow nanofiber; preparation of SnCl 2 The solution is used for dipping the tin oxide hollow nano-fiber and calcining to uniformly load tin oxide seed crystals on the surface of the tin oxide hollow nano-fiber; adding trisodium citrate into mixed solution of ethanol and water, and adding SnCl 2 ยท2H 2 Adding O into the mixed solution, and adding SnO with crystal seeds on the surface 2 And (3) carrying out hydrothermal reaction on the nano fibers, and after the reaction is finished, taking out the precipitate, drying and calcining to obtain the gas sensitive material. The gas sensor prepared by the invention has the advantages of higher sensitivity to formaldehyde gas and good selectivity to interference gas. |
