| titleOfInvention | Sensitive material capable of simultaneously responding to hydrogen sulfide and sulfur dioxide |
| abstract | The invention relates to a sensitive material simultaneously responding to hydrogen sulfide and sulfur dioxide, which is characterized in that Al is used 2 O 3 、Dy 2 O 3 And Nd 2 O 3 To form the nanometer powder material. The preparation method comprises the following steps: co-dissolving aluminum salt, dysprosium salt and neodymium salt in acetic acid aqueous solution, dripping citric acid aqueous solution and isopropanol aqueous solution, ultrasonically oscillating to clarify, heating and refluxing, volatilizing 1/4 moisture, cooling to obtain gel, infrared drying the gel, grinding, two-stage roasting, and naturally cooling to obtain the final product 2 O 3 、Dy 2 O 3 And Nd 2 O 3 To form the composite powder material. The gas sensor made of the sensitive material provided by the invention can simultaneously measure trace hydrogen sulfide and sulfur dioxide in the air on site without being interfered by other common coexisting molecules. |
