N-doped carbon nanopipe-arrayed mesoporous carbon (N-CMK-5) with double-pore system, large surface area (992 m2/g), and high nitrogen amount (5.2 at.%) was synthesized by a simplified template route. In this route, mesoporous silica was directly used instead of using time-consuming aluminosilicate as a template and the carbonization process occurred in a nitrogen atmosphere instead of a vacuum. Furthermore, CMK-3, N-doped CMK-3, and CMK-5 ordered mesoporous carbons (OMCs) were compared with the as-prepared N-doped CMK-5 (N-CMK-5) to investigate the effect of microstructure on the electrochemical activity of OMCs. N-CMK-5 exhibited higher electrochemical activity than the other OMCs because it has more exposed defective sites and nitrogen active species. The developed N-CMK-5-based electrochemical sensor showed good practical application for the electrochemical detection of pesticide amitrole in real water sample. This work contributes a simplified route to synthesize tubular N-CMK-5 carbon and provides valuable information on the design of high-performance carbon electrode materials.

N掺杂碳纳米管排列的介孔碳的简化合成,用于电化学检测酰胺

带有双孔系统的N掺杂碳纳米管阵列介孔碳(N-CMK-5),大表面积(992 m 2)/ g),并通过简化的模板路线合成了高氮含量(5.2 at。%)。在这种方法中,直接使用介孔二氧化硅而不是使用费时的硅铝酸盐作为模板,并且碳化过程是在氮气气氛中而不是在真空中发生的。此外,将CMK-3,N掺杂CMK-3和CMK-5有序介孔碳(OMC)与已制备的N掺杂CMK-5(N-CMK-5)进行了比较,以研究微结构对OMC的电化学活性。N-CMK-5具有比其他OMC更高的电化学活性,因为它具有更多暴露的缺陷位点和氮活性物质。基于N-CMK-5的电化学传感器在实际水样中农药铵的电化学检测中具有良好的实际应用。
