The synthesis of heterojunction materials is regarded as an efficient way to enhance catalytic activities in various catalytic reactions. However, the existing fabrication approaches often rely on complex multi-step synthesis process. In this work, we fabricate sweater-ball shaped nanostructured MOF/TMS (Ni-MOF/NiS) heterojunction by one-pot, one-step solvothermal method. According to the results of discrete Fourier transform (DFT) calculations and experiments, the formation of Ni-MOF/NiS heterojunction interfaces improves electron transfer and charge redistribution, and increases the adsorption energy of glucose molecules as well, which is conducive to enhance electrochemical activity of electrode materials. The as-prepared Ni-MOF/NiS heterojunction exhibit enhanced glucose sensitivity, wide detection range and low detection limit. This study paves the way towards the development of MOF-based heterojunctions for electrochemical applications.
异质结材料的合成被认为是提高各种催化反应中催化活性的有效方法。然而，现有的制备方法通常依赖于复杂的多步合成过程。在这项工作中，我们通过一锅一步溶剂热法制备了毛衣球状纳米结构的MOF/TMS（Ni-MOF/NiS）异质结。根据离散傅里叶变换（DFT）计算和实验结果，Ni-MOF/NiS异质结界面的形成改善了电子转移和电荷重新分布，同时也增加了葡萄糖分子的吸附能，这有利于提高电极材料的电化学活性。所制备的Ni-MOF/NiS异质结表现出增强的葡萄糖敏感性、宽检测范围和低检测限。这项研究为基于MOF的异质结在电化学应用方面的发展铺平了道路。
