ABSTRACT

Covalent organic frameworks, characterized by their stable porous layered structures, are promising candidates for supercapacitor electrode materials. In this study, a benzimidazole-based COF material (DAB-BTC-COF) was synthesized via thermal reaction using 3,3',4,4'-biphenyltetramine and 1,3,5-benzenetricarboxylic acid as monomers. The structural integrity of the synthesized material was confirmed through X-ray diffraction and Fourier-transform infrared spectroscopy. Electrochemical evaluations revealed that DAB-BTC-COF exhibits electric double-layer capacitive behavior with excellent reversibility in acidic electrolytes. Electrochemical impedance spectroscopy indicated negligible charge transfer resistance and high conductivity, while galvanostatic charge-discharge tests demonstrated high-rate capability, superior power density, and robust cycling stability.
