| titleOfInvention | Method for preparing nickel oxide/zinc oxide heterojunction nanometer materials |
| abstract | The invention discloses a method for preparing nickel oxide/zinc oxide heterojunction nanometer materials. By the aid of the method, the technical problem of low sensitivity of nickel oxide/zinc oxide heterojunction nanometer materials prepared by the aid of existing methods can be solved. The technical scheme includes that the method comprises synthesizing nickel oxide/zinc oxide heterojunction pre-sintered powder from mixed solution by the aid of a one-step hydrothermal process; calcining the nickel oxide/zinc oxide heterojunction pre-sintered powder to obtain the nickel oxide/zinc oxide heterojunction nanometer materials. The mixed solution is prepared from nickel acetate tetrahydrate, zinc nitrate hexahydrate and sodium hydroxide. The method has the advantages that the method only includes one reaction step instead of two reaction steps in the prior art, and the reaction time is shortened and is 12 h instead of the reaction time of 60 h in the prior art; as shown in gas sensitivity tests, the working temperatures of gas sensors made of the nickel oxide/zinc oxide heterojunction nanometer materials prepared by the aid of the method are lowered and are 200 DEG C instead of the working temperatures of 330 DEG C in the prior art; the sensitivity of the gas sensors for 100 ppm acetone gas is improved and reaches 15-17 instead of the sensitivity of 12 in the prior art. |
