Abstract
The invention discloses a silver-modified micron tubular indium oxide nitrogen dioxide gas-sensitive material and a preparation method thereof, and belongs to the technical field of sensing materials and preparation thereof. The preparation method of the nitrogen dioxide gas-sensitive material specifically comprises the following steps: dissolving 1, 4-terephthalic acid in N, N-dimethylformamide, adding indium salt, uniformly dispersing, performing thermal synthesis and calcining to obtain micron tubular indium oxide, dispersing the micron tubular indium oxide in a mixed solution of silver nitrate and sodium citrate, and dropwise adding a sodium borohydride solution to obtain the silver-modified micron tubular indium oxide nitrogen dioxide gas-sensitive material. The silver-modified micron tubular indium oxide prepared by the invention has relatively high sensitivity to NO2 at room temperature, and is a high-performance gas sensitive material with potential application value.
