Nitrogen-doped graphene nanosheet (N-SEGN) with pyrrolic nitrogen and 5-9 vacancy defects has been successfully prepared from a hydrothermal reaction of tetra-2-pyridinylpyrazine and sonoelectrochemistry-exfoliated graphene nanosheet, with point defects. Additionally, based on the same reaction using chemically reduced graphene oxide, nitrogen-doped chemically reduced graphene oxide (N-rGO) with graphitic nitrogen was prepared. The N-SEGN and N-rGO were used as a non-enzymatic H₂O₂ sensors. The sensitivity of the N-SEGN was 231.3 μA·mM^-1·cm^-2, much greater than 57.3 μA·mM^-1·cm^-2 of N-rGO. The N-SEGN showed their potential for being a H₂O₂ sensor.

通过四-2-吡啶基吡嗪与声电化学剥落的石墨烯纳米片的水热反应，成功地制备了具有吡咯氮和5-9个空位缺陷的氮掺杂石墨烯纳米片（N-SEGN）。另外，基于使用化学还原的氧化石墨烯的相同反应，制备了具有石墨氮的氮掺杂的化学还原的氧化石墨烯（N-rGO）。N-SEGN和N-rGO用作非酶H ₂ O ₂传感器。的N SEGN的灵敏度为231.3μA·毫^-1 ·厘米^-2，远远大于57.3μA·毫^-1 ·厘米^-2的N- RGO的。N-SEGN显示出其成为H ₂ O _2的潜力 传感器。
