Abstract

We investigated the effect of specific surface area on the electrochemical properties of NiCoO (NCO) for glucose detection. NCO nanomaterials with controlled specific surface areas were prepared by additive-assisted hydrothermal synthesis, and self-assembled nanostructures with urchin-, pine-needle-, tremella-, and flower-like morphologies were obtained. The novelty of this method is the systematic control of chemical reaction routes assisted by the addition of different additives during synthesis, which results in the spontaneous formation of various morphologies without any difference in the crystal structure and chemical states of the constituent elements. Such morphological control of NCO nanomaterials leads to considerable changes in the electrochemical performance for glucose detection. Combined with materials characterization, the relationship between the specific surface area and the electrochemical performance is discussed for glucose detection. This work can provide scientific insights for tailoring the surface area of nanostructures, which determines their functionality for potential applications in glucose biosensors.

摘要

我们研究了比表面积对用于葡萄糖检测的 NiCoO（NCO）电化学性能的影响。通过添加剂辅助水热合成制备了具有可控比表面积的 NCO 纳米材料，并得到了具有刺猬状、松针状、银耳状和花朵状形貌的自组装纳米结构。该方法的新颖之处在于通过在合成过程中添加不同的添加剂来系统地控制化学反应途径，从而在不改变组成元素的晶体结构和化学状态的情况下，自发形成各种形貌。NCO 纳米材料的这种形态控制导致其对葡萄糖检测的电化学性能发生了显著变化。结合材料表征，讨论了比表面积与葡萄糖检测电化学性能之间的关系。这项工作可以为调整纳米结构的表面积提供科学见解，这决定了它们在葡萄糖生物传感器等潜在应用中的功能。
