摘要

介绍了一种合成金属/金属硫化物层次化孔阵列复合材料的新工艺。也就是说，在胶体球模板的辅助下，通过两步电沉积法在Ni有序碗状微纳米阵列上原位构建了一层Ni- co -s纳米片。这种生长的分层复合材料可以增加比表面积，并为电催化反应提供更多的活性位点。该材料对葡萄糖具有较高的催化活性，灵敏度为1210.1 μM·mM-1cm-2，线性范围为0.5 μM ~ 2.0 mM。该研究为平面非酶促葡萄糖传感器的开发提供了另一种候选材料。

Growth of Ni-Co-S Nanoflakes on Ni Bowl-Like Micro/Nano Array as a Non-Enzymatic Electrode for Detection of Glucose

A new synthetic procedure to Metal/metal sulfide hierarchical pore array composites was described. That is, a layer of Ni-Co-S nanoflakes was in situ constructed on the Ni ordered bowl-like micro/nanoarrays through a two-step electrodeposition method with the assistance of a colloidal sphere template. Such as-grown hierarchical composites could increase the specific surface areas and provide more active sites for electrocatalytic reactions. It exhibited a high catalytic activity to glucose, with a high sensitivity of 1210.1 μM‧mM-1cm-2 and a wide linear range from 0.5 μM to 2.0 mM. This work provides another candidate material for the development of planar non-enzymatic glucose sensors.
