In this paper, nitrogen-doped graphene (N-G) was first produced by an eco-friendly hydrothermal method using low-cost industrial material (NH₄)₂CO₃ 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.

本文首先以低成本的工业材料（NH ₄）₂ CO ₃为氮源，通过生态友好的水热法制备了掺氮石墨烯（NG）。通过还原HAuCl ₄合成了氮掺杂的石墨烯负载的金（Au / NG）纳米颗粒（NPs）用柠檬酸钠作为还原剂通过微波辐照工艺。通过扫描电子显微镜，透射电子显微镜，X射线衍射和X射线光电子能谱表征NG和Au / NG NP。结果表明，金纳米颗粒（AuNPs）有效地负载在NG表面。Au / NG NPs的循环伏安法和电化学阻抗谱表明，它们是具有良好电化学性能的出色电极材料。
