采用两步热处理法制备了一种新型的分级Au/Ni/掺硼金刚石（BDD）异质结构电极。透射电子显微镜（TEM）证实了分级结构的Au/Ni纳米颗粒嵌入BDD表面的异质结构。采用循环伏安法和安培检测法对电极的电化学性能进行了测试。与Au/BDD和Ni/BDD电极相比，Au/Ni/BDD电极在葡萄糖检测中表现出增强的催化活性和稳定性。在最佳NaOH浓度和施加电位下，Au/Ni/BDD电极的检测范围为0.005 - 32 mM，灵敏度为1229.5 μ AmM − 1 cm − 2，并且具有良好的长期稳定性（1个月后保持初始电流的94.8%）。此外，该电极的检出限为2 μ M（S/N = 3），具有良好的选择性和重现性。最后，对Au/Ni/BDD电极催化活性和稳定性的原因进行了探讨。
A novel hierarchical Au/Ni/boron-doped diamond (BDD) heterostructure electrode was fabricated by two-step heat-treatment. The heterostructure that hierarchical Au/Ni nanoparticles are embedded on the surface of BDD was demonstrated by transmission electron microscope (TEM). Cyclic voltammetry (CV) and amperometric detection were used to test electrochemical properties of the prepared electrodes. The Au/Ni/BDD electrode exhibited enhanced catalytic activity and stability in glucose detection, as compared to that of the Au/BDD and Ni/BDD electrodes. On the optimal NaOH concentration and applied potential, the Au/Ni/BDD electrode exhibited an extremely wide detection range of 0.005–32 mM with high sensitivity of 1229.5 μAmM− 1 cm− 2 and an excellent long-term stability (maintains 94.8% of initial current after one month). In addition, the prepared electrode also exhibited a low detection limit of 2 μM (S/N= 3), good selectivity and reproducibility. At last, the reasons for enhanced catalytic activity and excellent stability of Au/Ni/BDD electrode were discussed.
