Abstrakt: Glucose holds significant importance in disease diagnosis as well as beverage quality monitoring. The high-efficiency electrochemical sensor plays a crucial role in the electrochemical conversion technology. Ni(OH) 2 nanosheets are provided with high specific surface area and redox activity that are widely used in electrochemistry. Conductive metal-organic frameworks (cMOFs) perfectly combine the structural controllability of organic materials with the long-range ordering of inorganic materials that possess the characteristic of high electron mobility. Based on the above considerations, the combination of Ni(OH) 2 and Ni-HHTP (HHTP=2,3,6,7,10,11-hexahydroxytriphenylene) as an electrode modification material is designed to enhance electrochemical performance. In this work, to improve glucose detection, a sequence of Ni(OH) 2 @NiCo-HHTP and NiM-LDH@Ni-HHTP (M=Co 2+ , Mn 2+ , Cu 2+ , LDH=layered double hydroxide) are successfully synthesised by doping metals into Ni-HHTP and Ni(OH) 2 , respectively. As a result, NiCu-LDH@Ni-HHTP showed the best excellent glucose detection sensitivity.
