Nano-construction of CuO nanorods decorated with g-C3N4 nanosheets (CuO/g-C3N4-NS) as a superb colloidal nanocatalyst for liquid phase C-H conversion of aldehydes to amides

Herein, we describe an intelligent strategy to fabricate nanosheets of graphitic carbon nitride (g-C3N4) decorated with nanorods copper oxide (CuO NRs). Then, the catalytic activity of CuONRs/g-C3N4-NS was developed for the synthesis of primary amides in water. The morphology of CuO and its synergetics effect with nanosheets g-C3N4 a major role in the yield of products. Furthermore, hydroxylamine hydrochloride (NH2OH center dot HCl) due to availability and affordability was used as a suitable substitute for ammonia source. The findings demonstrate that this layer nanostructure is a superb catalyst for converting various derivatives of aldehyde to their corresponding amides. The current protocol can be useful criterion in the synthesis and stabilization of metal oxides and provides new insight in organic transformation. (C) 2021 Elsevier B.V. All rights reserved.
