Abstract
A new nanocomposite system based on carbon supported CuO material was designed and confirmed by various techniques, such as XRD, FTIR, UV–Vis, PL and FE-SEM. A straightforward and scalable procedure that involves carbonizing lignin deposited on the surface of copper oxide nanoparticles produces CuO/C nanocomposites. In this study, CuO/C nanocomposites were used as photocatalysts for a one-pot synthesis of quinazolines under blue light irradiation. The catalyst showed excellent activity for synthesizing quinazolines (8 examples) with higher yield (84–94%) and easy recovery from the reaction mixture. The recovered CuO/C nanocomposites were used for 5 consecutive cycles, without significant loss of its catalytic activity. The synthesized compounds were also tested for antibacterial activity, and they exhibited considerable activity. This research will pave the way for the investigation of the use of lignin-derived carbon as a substrate for other types of nanoparticles, resulting in the creation of novel, eco-friendly catalysts for a variety of organic reactions.
期刊介绍：
Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
