| titleOfInvention | High-selectivity composite gas-sensitive material for detecting acetic acid gas in air |
| abstract | The invention discloses a high-selectivity composite gas-sensitive material for detecting acetic acid gas in air, and belongs to the technical field of gas-sensitive materials. The composite gas-sensitive material consists of C 3 N 4 -ZnO wherein C 3 N 4 The mass of (A) is 5 of the total mass of the material-20%. The indirectly heated gas-sensitive sensor made of the composite material as the sensitive material has the sensitivity of 0.1ppm acetic acid of 1.2-1.4 at the working temperature of 300 ℃, the sensitivity of the element to 1000ppm acetic acid reaches 290-350, and the sensitivity to the same 1000ppm acetone, formaldehyde, ethanol, acetaldehyde and ammonia gas is below 31, which shows that C is C 3 N 4 The sensitivity of zinc oxide to acetic acid gas is improved, the gas sensitivity selectivity of zinc oxide to acetic acid gas is improved, the concentration of acetic acid in air can be rapidly detected, and the interference of acetone, formaldehyde, ethanol, acetaldehyde, ammonia gas and other gases is eliminated. |
