摘要

Traditional electro-organic synthesis methods for sulfonamides often suffer from low catalytic efficiency, long reaction times, and the use of environmentally harmful reagents, limiting their practical applications and sustainability. This study explores the utilization of cobalt nanoparticles supported on GO enhanced with the MIL-100@Co MOF in a PAOCl as an electrolyte and SO2 trapping agent for the electro-catalytic synthesis of sulfonamides via C-H activation reaction. The synthesized catalyst was characterized utilizing various analytical techniques, including FT-IR, BET, SEM, EDS, EDX mapping, TGA, CV, and XPS, to confirm its structural integrity and elemental composition. The catalytic performance was evaluated in terms of yield and reaction time, demonstrating an impressive 92–97%yield of sulfonamides 4(a-k) within just 45 min at ambient temperature and atmospheric pressure, using a current of 10 mA. This performance surpasses that of traditional methods employing other cathode materials, which often suffer from low yields and prolonged reaction times. The incorporation of Co nanoparticles enhances catalytic efficiency, while PAOCl serves as both an electrolyte and SO₂ trapping agent. Additionally, the MIL-100@Co MOF provides a robust support structure with a high surface area, improving reactivity in the electrochemical environment. Overall, this work highlights the potential of MIL-100@Co MOF composites in a PAOCl as effective catalytic system for sustainable sulfonamides 4(a-k) synthesis in electrochemical applications.
