Two copper‐based Cu 3 (btc) 2 and Cu(Im) 2 metal–organic frameworks are synthesized and annealed to form nanoporous Cu/Cu 2 O@C and Cu@N‐C nanoparticles for utilization as catalysts in the reduction reaction of aromatic nitro compounds to aromatic amines. All synthesized MOF compounds and MOF‐derived nanoparticles are characterized using XRD, Raman spectroscopy, TGA, SEM‐EDX, and XPS methods. Also, the pore‐size distribution and surface area of the MOF‐derived Cu/Cu 2 O@C and Cu@N‐C nanoparticles are characterized by the BJH and BET methods. After characterization, the catalysts Cu/Cu 2 O@C and Cu@N‐C are catalytically tested for the reduction reactions of various aromatic nitro compounds chemically by monitoring with a UV/Vis spectrometer. Both catalysts exhibit remarkable results compared with those in the literature. Also, the Cu/Cu 2 O@C catalyst shows better results than the Cu@N‐C catalyst.
