| titleOfInvention | Method for preparing zinc-oxide/simple-substance-carbon core-shell structure |
| abstract | The invention discloses a method for preparing a zinc-oxide/simple-substance-carbon core-shell structure. The method is used for solving the technical problem that a zinc-oxide gas-sensing material prepared with an existing method is low in sensitivity. The method in the technical scheme includes the steps that the surfaces of zinc-oxide nanometer particles are modified through a silane coupling agent 3-aminopropyltriethoxysilane, then glucose molecules are connected to the surfaces of the modified zinc-oxide nanometer particles to prepare a precursor material, and the glucose molecules are heated and carbonized to obtain the zinc-oxide/simple-substance-carbon core-shell structure. As hazardous chemicals are avoided, the production process is safer; according to testing, the zinc-oxide/simple-substance-carbon core-shell structure prepared with the method is stable in property, and has the good gas-sensing performance, and particularly, the sensitivity to low-concentration acetone gas is obviously increased; the sensitivity of the zinc-oxide/simple-substance-carbon core-shell structure to acetone gas of 100 ppm is increased to 38-43 from 26.1 of the background technology; the stability of gas sensitive elements is prolonged to 70-90 days from 30 days of the background technology, and the stability is remarkably improved. |
