Graphitic n是什么意思
WebJun 5, 2024 · Graphitic N possesses the highest thermal stability, whereas pyrrolic N has the lowest thermal tolerance [23]. Thus, the synthesis temperature plays a crucial role in the N doping content and configuration in carbon allotropes [24]. Besides, N sources and synthesis conditions (ambient or inert) can also affect N bonding configurations. WebNov 18, 2024 · They concluded that graphitic nitrogen, as found in the sample with a low N content, is the n-type dopant, whereas pyridinic and pyrrolic found at higher N concentration are p-type dopants. Contrarily, Lu et al. [ 32 ] observed transformation from p-type N-doped graphene to n-type, when nitrogen content was increased from 2.1 to 5.6%.
