Magnetic COF-Supported Palladium Nanoparticles: An Efficient and Sustainable Photocatalyst for Carbonylative Coupling Reactions under CO Gas-Free and Visible-Light Irradiation

This study presents a sustainable and green method for converting visible light into valuable products. To accomplish this, a Pd NP-doped COF-based magnetic photocatalyst (Pd/CoFe2O4@CTF) was created. The catalytic activity of the heterogeneous photocatalyst was examined in the carbonylative coupling reactions for the preparation of amides, esters, and 2-aryl quinazolinones after it had been characterized using a variety of microscopic and spectroscopic techniques, including FT-IR, PXRD, TGA, SEM, EDAX, TEM, UV-DRS, Matt-Schottky, PL, EIS, ICP, VSM, and BET. This study used the optical method for the first time to create the 2-aryl quinazolinone ring from 2-aminobenzamide and iodobenzene. The desired products can be produced in medium to good yields by using the optical method and under suitable reaction conditions. The benefits of this study include the use of visible light as a renewable and environmentally friendly source, mild reaction conditions, a simple separation method, a reduction in byproducts, and cost and time savings. Under optimal conditions, the catalyst’s stability and recyclability were investigated. It showed excellent reversibility up to 6 times without significantly losing activity.
