英文摘要： Graphene through nitrogen doping will display more excellent biocompatibility and higher activity. It is undoubted that design and synthesis of nitrogen doped graphene(NG) with high specific surface area can further demonstrate its outstanding performance, and greatly broaden its application area. Considering these aspects, on the basis of synthesis of three dimensional(3D) NG using metallic and ceramic templates with porous structure and combining with the theoretical and experimental researches on electrocatalytic activity for NG with different nitrogen content and configuration,this project will construct new platforms for the determination of small biomolecules. In addition, the influeneces of NG structure, layers, nitrogen content and configuration doped into graphene structure on its electrocatalytic performance are investigated systematically. As a result, the interaction mechanisms between NG and biomolecules or oxygen molecules can be revealed clearly. On the basis of the above researches, the NG-based biosensors are used to determine small biomolecules such as glucose and lactic acid, which will offer theoretical support for the establishment of bioanalytical methods with high sensitivity and selectivity.So the researches of this project have much higher theoretical value and practical application pro
