- Abstract
A comprehensive vision has been promoted for straightforward oxidative amidation, deploying a majority of amines and aldehydes via a robust and novel nano-catalyst of W/Co@g-C3N4. This approach would yield the primary, secondary, and tertiary amides with excellent efficiency experiencing mild conditions, in which the environmentally benign oxidizing agent of TBHP was predominantly used, holding remarkable attributes such as cost-effectiveness as well as facile approachability. More specifically, simultaneously embedding of W and Co on the surface of g-C3N4 has been an integral part in effectually progressing direct operation of amidation reaction in comparison with pure g-C3N4. The most important point highlighted in this work is the productive contribution of materials choice in designing as well as manufacturing approaches with respect to new required products while giving the most extreme level of accessible quality and efficiency with the most reduced level of costs. Emphatically, a variety of extraordinary merits can be awarded to this as-prepared catalyst, such as notable activity, reasonable recyclability, sustainable nature, and easy work-up. Moreover, a simple process was conducted to synthesize W/Co@g-C3N4 evaluated by employing FT-IR, XRD, SEM, EDX, and TGA. Highlights: Nano-W/Co@g-C3N4 was introduced for the first time as a robust and efficient catalyst. Employing of tungsten and cobalt revealed a considerable shift in the catalytic performance of g-C3N4. Short reaction time as well as high yield with respect to the reported literatures for formation of amide bond through direct oxidative amidation. W/Co@g-C3N4 could be used in five consecutive runs without any significant drop in activity.
