An efficient and robust electrocatalyst is significant for glucose biosensing. The emergence of metal–organic framework (MOF) derived materials opens up new avenues for the development of high-performance glucose sensing catalysts. Herein, MOF derived nickel-cobalt hydroxide supported on conductive copper sheet (NiCo-OH/Cu sheet) is prepared at room temperature. The as-obtained NiCo-OH is endowed with three-dimensional network structure which enables the effective exposure of active materials, sufficient contact between glucose molecule and catalyst. The NiCo-OH/Cu sheet is revealed as good glucose electrochemical sensing material with a wide linear range of 0.05∼6.0 mM and a high sensitivity of 1340 μA mM⁻¹ cm⁻². Additionally, the as-fabricated NiCo-OH/Cu sheet displays good anti-interference ability and long-term stability.

MOF 衍生的 NiCo 氢氧化物，用于高效非酶葡萄糖生物传感

高效且稳定的电催化剂对于葡萄糖生物传感具有重要意义。金属有机骨架（MOF）衍生材料的出现为高性能葡萄糖传感催化剂的开发开辟了新途径。在此，在室温下制备负载在导电铜片（NiCo-OH/Cu片）上的MOF衍生的氢氧化镍钴。所得NiCo-OH具有三维网络结构，使得活性材料有效暴露，葡萄糖分子与催化剂充分接触。 NiCo-OH/Cu片被证明是良好的葡萄糖电化学传感材料，具有0.05∼6.0 mM的宽线性范围和1340的高灵敏度μA mM ^-1 cm ^-2。此外，所制备的NiCo-OH/Cu片具有良好的抗干扰能力和长期稳定性。
