This research work reports the synthesis of copper oxide (CuO) nanoparticles supported on activated carbon by a simple impregnation method using 2-propanol as a green solvent, followed by calcination. The synthesized CuO@C is used as an efficient heterogeneous nanocatalyst for the synthesis of 2H-indazoles and quinazolines utilizing commercially available 2bromobenzaldehydes, primary amines, and sodium azide under ligand-free and base-free conditions. The present methodology demonstrates the formation of new N−N, C−N, and C�N bonds under one-pot reaction conditions using PEG-400 as a green solvent. The reaction pathways are supported by control experiments and mechanistic elucidation. Further, the synthesized catalyst was characterized by a range of microscopic and spectroscopic techniques such as powdered X-ray diffraction, fourier transform infrared spectroscopy, field emission scanning electron microscopy, energy-dispersive X-ray, UV−vis, X-ray photoelectron spectroscopy, high-resolution transmission electron microscopy, and BET-BJH analysis. Importantly, the study focused on the recyclability of the catalyst and successfully showed gram-scale production. Significantly, our active catalyst exhibited an outstanding performance in the oxygen evolution reaction, with an overpotential of 290 mV and a swallow Tafel slope of 91 mV dec −1 .
