采用直接混合法制备了一种新型锌配合物[Zn(C11H15N3)2Cl2]与碳粉复合的导电碳糊电极。用X-射线单晶衍射法和元素分析表征了[Zn(C11H15N3)2Cl2]的结构。详细研究了新型锌配合物改性CPE的电化学行为和电催化性能。这种本体修饰的锌CPE对过氧化氢和亚硝酸盐的还原表现出良好的电催化活性。结果重现性好，检测下限低于目前报道的使用其他修饰电极的结果。此外，这种本体修饰的CPE具有显著的长期稳定性，制备简单，材料便宜，这对电化学传感器的实际应用具有重要意义。
A conductive carbon paste electrode (CPE) comprising a new zinc complex of [Zn(C11H15N3)2Cl2] and carbon powder was fabricated by the direct mixing method. The structure of [Zn(C11H15N3)2Cl2] was characterized by X-ray crystallography and elemental analysis. The electrochemical behavior and electrocatalysis of the new zinc complex modified CPE (Zn–CPE) have been studied in detail. This bulk-modified Zn–CPE displayed good electrocatalytic activity toward the reduction of the hydrogen peroxide and nitrite. The results are reproducible with a lower detection limit than reported currently using other modified electrodes. Also, this bulk-modified CPE exhibits remarkable long-term stability, simple preparation, and inexpensive material, which is important for practical application on electrochemistry sensors.
