2D metal-organic frameworks (MOFs) are considered as promising electrochemical sensing materials and have attracted a lot of attention in recent years. Compared with bulk MOFs, the construction of 2D MOFs can increase the exposure of active sites by obtaining a larger surface area ratio. Herein, a facile one-pot hydrothermal synthesis of pyridine-regulated lamellar Ni-MOFs with ultrathin and well-defined 2D morphology is described. Compared with the bulk structure, the 2D lamellar Ni-MOF has higher surface area and active site density, showing better electrochemical glucose sensing performance. The 2D lamellar Ni-MOF exhibits a fast amperometric response of less than 3 s and a high sensitivity of 907.54 µA mm cm toward glucose with a wide linear range of 0.5-2665.5 µm. Furthermore, the 2D lamellar Ni-MOF also possesses excellent stability and reproducibility, and can be used to detect glucose with high accuracy and reliability in different environments.
二维金属有机框架材料（MOFs）被认为是很有前景的电化学传感材料，近年来受到了广泛关注。与块状MOFs相比，二维MOFs的构建可以通过获得更大的表面积比来增加活性位点的暴露。在此，描述了一种简便的一锅水热合成法，用于制备具有超薄且明确二维形态的吡啶调控层状镍基金属有机框架材料（Ni-MOFs）。与块状结构相比，二维层状Ni-MOF具有更高的表面积和活性位点密度，表现出更好的电化学葡萄糖传感性能。二维层状Ni-MOF对葡萄糖的安培响应速度快于3秒，灵敏度高达907.54 μA mm cm，线性范围宽达0.5 - 2665.5 μM。此外，二维层状Ni-MOF还具有出色的稳定性和重现性，可用于在不同环境中高精度、可靠地检测葡萄糖。
