| titleOfInvention | Ozone gas-sensitive material and preparation method thereof, ozone gas-sensitive device and preparation method thereof |
| abstract | The invention relates to an ozone gas-sensitive material and a preparation method thereof, and an ozone gas-sensitive device and a preparation method thereof. The ozone-sensitive material is Co 3 O 4 The nano powder is in a hollow cubic structure and has a particle size of 100-250 nm. The preparation method of the gas sensitive material comprises the following steps: mixing a tin chloride aqueous solution and a citric acid aqueous solution to obtain a solution I; mixing a cobalt chloride aqueous solution with the solution I, adding NaOH or KOH, stirring, adding NaOH or KOH again, and stirring to obtain a mixed solution, wherein the molar ratios of the NaOH or KOH to the tin chloride added for the first time and the second time are 6-10: 1 and 30-50: 1 respectively; carrying out hydrothermal reaction on the mixed solution, carrying out suction filtration, washing and drying on a reaction product to obtain a precursor, heating and calcining the precursor to obtain Co 3 O 4 And (3) nano powder. The gas sensitive material of the invention has high sensitivity and good selectivity to ozone, and the prepared gas sensitive device has a detection function of high sensitivity to ozone gas. |
