Abstract
In this study, for the first time, Graphene Quantum Dots (QGD) was used as a green catalyst for the reduction of aromatic nitro compounds under the Light-Emitting Diode (LED) and metal-free conditions. Prepared graphene quantum dots were characterized using different techniques such as Transmission Electron Microscopy (TEM), X-ray Photoelectron Spectroscopy (XPS), and absorption and emission spectroscopy. Using graphene quantum dots, structurally different aromatic nitro compounds were reduced to corresponding amines at room temperature and gave corresponding amines at high to excellent yields. Finally, the kinetic reduction reaction of different substitutions nitrobenzene (ortho, meta, and para) and the effect of substitution on rate were studied.
