| titleOfInvention | Nitrogen-phosphorus co-doped graphene quantum dot and preparation method thereof |
| abstract | The invention provides a nitrogen-phosphorus co-doped graphene quantum dot and a preparation method thereof, wherein the preparation method comprises the following steps: adding 1,3, 6-trinitropyrene and nitrogen and phosphorus co-doped source into deionized water according to the weight ratio of 1: 20-30, adjusting the pH value to 11-12, performing ultrasonic dispersion, performing hydrothermal reaction at 160-200 ℃ for 5-8 h, cooling, filtering, dialyzing, and freeze-drying to obtain the nitrogen and phosphorus co-doped graphene quantum dot. The method takes a nitrogen-phosphorus co-doped source as a nitrogen source and a phosphorus source at the same time, avoids introducing other impurity atoms, is prepared by adopting a one-step simple hydrothermal method, has simple process and low prices of raw materials and equipment, and is suitable for industrial production. The prepared nitrogen-phosphorus co-doped graphene quantum dots and anatase TiO 2 The photocatalytic composite material obtained after compounding has photocatalytic efficiency reaching nearly 90% in 10 minutes under the irradiation of ultraviolet light, and shows excellent photocatalytic performance. |
