辐射合成镧系基导电金属有机骨架及其赝电容性能
Radiation synthesis of lanthanide-based conductive metal-organic framework and their pseudocapacitive performance
摘要
Abstract
In this study,a lanthanide-based conductive metal-organic framework(Ho-HHTP)was synthesized via gamma-ray irradiation technology and systematically evaluated for its pseudocapacitive behavior.Powder X-ray diffraction confirmed the successful synthesis of Ho-HHTP,while high-resolution transmission electron microscopy revealed its ultrathin nanosheet-like morphology and well-defined one-dimensional channel architecture.Cyclic voltammetry analysis showed typical symmetric redox peaks indicating dominant surface-controlled pseudocapacitive charge storage.Quantitative kinetic analysis revealed that the pseudocapacitive contribution accounted for 82.18％of the total capacitance at a scan rate of 30 mV/s.Electrochemical measurements further demonstrated a high specific capacitance of 215.5 F/g at 1 A/g,along with robust rate capability—retaining substantial capacitance even at elevated current densities.Electrochemical impedance spectroscopy indicated low ohmic resistance(～2.5 Ω)and charge-transfer resistance(～3.8 Ω),corroborating efficient interfacial charge transfer and rapid ion diffusion kinetics.Collectively,this work presents a radiation-enabled synthetic route for lanthanide-based conductive MOFs and establishes Ho-HHTP as a highly promising electrode material for next-generation supercapacitors.关键词
