| titleOfInvention | Amorphous tin dioxide modified multilayer cobalt oxide material, preparation method thereof and formaldehyde gas-sensitive detection application |
| abstract | The invention discloses an amorphous tin dioxide modified multilayer cobalt oxide material which is characterized by comprising a multilayer cobalt oxide shell structure nested layer by layer, wherein the outer diameter of the multilayer cobalt oxide shell structure is 1-2 mu m, and each shell layer of the multilayer cobalt oxide shell structure is uniformly modified with amorphous tin dioxide crystals. The preparation method comprises the steps of calcining the cobalt-based coordination polymer precursor at high temperature to obtain a cobalt oxide multilayer shell structure; and immersing the cobalt oxide multilayer shell structure into an organic solvent, stirring, carrying out ultrasonic treatment until the cobalt oxide multilayer shell structure is uniformly dispersed, heating in an oil bath, and adding a tin source solution to carry out electric replacement reaction to obtain the amorphous tin dioxide modified multilayer cobalt oxide material. The invention can realize effective regulation and control of an electronic structure, improve the gas-sensitive response capability of the material, and realize high responsiveness, low detection temperature and low test limit detection of target gas. |
