| titleOfInvention | A kind of ammonia sensor loaded with platinum particles and its preparation method |
| abstract | The invention relates to an ammonia gas sensor loaded with platinum particles and a preparation method thereof, belonging to the field of gas sensors. The gas-sensitive material is composed of platinum particles and a graphene film, and the platinum particles are loaded on a graphene film carrier. The method includes: (1) preparing a graphene film for use; (2) modifying the graphene film obtained in step (1) with ultraviolet ozone for use; (3) converting the improved graphene film in step (2) Immerse in a platinum chloride solution, heat and keep warm the graphene film after dipping, so that chloroplatinic acid is decomposed into platinum particles, and the ammonia gas-sensitive material with platinum particles supported on the graphene film is obtained. In the present invention, the graphene film is firstly modified by ultraviolet ozone treatment, oxygen-containing functional groups are introduced, defect sites and adsorption sites are increased, and resistance characteristics and wettability are changed, and then platinum particles are loaded on the graphene film , the gas sensor prepared by the invention has excellent room temperature response performance to ammonia. |
