▎ 摘  要

In this paper, nitrogen-doped graphene (N-G) was first produced by an eco-friendly hydrothermal method using low-cost industrial material (NH4)(2)CO3 as the nitrogen source. Nitrogen-doped, graphene-supported gold (Au/N-G) nanoparticles (NPs) were synthesized through the reduction of HAuCl4 using sodium citrate as the reducing agent by a microwave irradiation process. The N-G and Au/N-G NPs were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. The results indicated that gold nanoparticles (AuNPs) were effectively loaded on the surface of N-G. Cyclic voltammetry and electrochemical impedance spectroscopy of the Au/N-G NPs suggested they are an excellent electrode material with good electrochemical properties.
