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 HO sensors. The sensitivity of the N-SEGN was 231.3 μA·mM·cm, much greater than 57.3 μA·mM·cm of N-rGO. The N-SEGN showed their potential for being a HO sensor.
通过四-2-吡啶基吡嗪与超声电化学剥离的具有点缺陷的石墨烯纳米片的水热反应，成功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）。此外，基于使用化学还原氧化石墨烯的相同反应，制备了具有石墨氮的氮掺杂化学还原氧化石墨烯（N-rGO）。N-SEGN和N-rGO被用作非酶过氧化氢传感器。N-SEGN的灵敏度为231.3μA·mM·cm，远高于N-rGO的57.3μA·mM·cm。N-SEGN显示出其作为过氧化氢传感器的潜力。
