Copper-Cobalt Bimetallic nanoparticles supported on Magnetic MOF Derived N-doped carbon as highly efficient Catalysts for the C–N coupling and one-pot multicomponent reaction

Magnetic metal-organic frameworks (MOFs) are promising precursors for generating diverse carbon-based nanostructures due to their facile recovery and separation, as well as their robust mechanical and thermal properties. In this study, a novel Cu-Co bimetallic nanoparticle supported on magnetic MOF derived N-doped carbon was successfully synthesized. The copper ions preloaded within the pores of the Co MOF provide abundant exposed Cu active sites. The pyrolysis treatment results in a hierarchical porous structure with a high surface area, contributing to mass transfer and enhancing reactant diffusion to the active sites. The developed catalyst was characterized extensively using FT-IR, XRD, BET, BJH, EDX, TGA, VSM, FE-SEM, ICP, and XPS techniques. The catalyst exhibited exceptional catalytic activity for C-N coupling and one-pot multicomponent reactions. This superior performance can be attributed to the synergistic effect between copper nanoparticles incorporated in the composite, as well as the highly porous N-doped carbon structure. The catalyst demonstrated remarkable stability, maintaining its activity without significant degradation after five consecutive reaction cycles. This innovative approach, capitalizing on the reinforcing interplay of structural and compositional advantages, opens up opportunities for the rational design and synthesis of highly efficient bimetallic nanoparticle catalysts supported on magnetic MOF-derived N-doped carbon.
