NOVELTY - Xenon difluoride and urea are placed in cups comprising three layers of quartz. Graphene oxide is?placed on top of three layers. Three-layered quartz glass is provided into Teflon (RTM: polytetrafluoroethylene) cup, and sealed. The Teflon (RTM: polytetrafluoroethylene) cup is provided to stainless steel tank and sealed. The stainless steel tank is provided into drying box, dried and cooled, to obtain fluorine and nitrogen-doped graphene oxide. The mass ratio xenon difluoride and urea is 0.8-1.2:0.8-1.2:50-150. USE - Preparation of fluorine and nitrogen-doped graphene oxide (claimed). DETAILED DESCRIPTION - Xenon difluoride and urea as nitrogen source are placed in cups comprising three layers of quartz. Graphene oxide is?placed on top of three layers, and xenon difluoride is provided in intermediate of three quartz glass, and urea is provided in lower of three layers of quartz glass. Three-layered quartz glass is provided into Teflon (RTM: polytetrafluoroethylene) cup, and sealed. The Teflon (RTM: polytetrafluoroethylene) cup is provided to stainless steel tank and sealed. The stainless steel tank is provided into drying box, dried at 200 plus minus 2 degrees C for 10-24 hours and cooled to room temperature, to obtain fluorine and nitrogen-doped graphene oxide. The mass ratio xenon difluoride and urea is 0.8-1.2:0.8-1.2:50-150.
