The efficient synthesis of transition-metal cobalt oxide nanoparticles (Co3O4 NPs) was achieved using the co-precipitation method without the use of costly and toxic solvents or complicated equipment. These reusable nanoparticles demonstrated high catalytic activity under microwave irradiation for the synthesis of organoselenium compounds with higher yields and milder reaction conditions.
For the efficient synthesis of transition-metal cobalt oxide nanoparticles (Co3O4 NPs) without using any costly and toxic solvent or complicated equipment, the co-precipitation method was used in this work. Using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), UV-Vis spectrophotometry, Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD), the prepared Co3O4 NPs were characterized and identified. The influence of prepared Co3O4 NPs on the developmental synthesis of some selenopyridine/quinoline derivatives under different microwave irradiation powers and irradiation times was investigated via click (reaction) chemistry. The reusable Co3O4 nanoparticles have high catalytic activity under microwave irradiation for the synthesis of organoselenium compounds with higher yields (> 90%), milder reaction conditions and shorter time without significantly decreasing the reaction rates and yields.
