A new approach for the sustainable fabrication of a CuO/ZnO@N-GQDs nanocomposite as a powerful nanocatalyst for multicomponent reactions is demonstrated.
Gram scale N-doped GQDs were prepared using a facile one-pot method by polymerization of nitrilotriacetic acid, showing a purity of over 99% without a dialysis process, a synthetic yield of 46% and a quantum yield of 45.8%.
Manganese ion (Mn2+) bonded nitrogen-doped graphene quantum dots (Mn(ii)-NGQDs) with water solubility have been successfully synthesized by a simple, one-pot hydrothermal carbonization, using sodium citrate, glycine and manganese chloride as raw materials.
