以廉价易得的工业材料（NH₄）₂CO₃为稳定剂和氮源，利用固体微波辐射的方法于水热条件下制备氮掺杂石墨烯（N-G）。实验过程中，以N-G为基底材料，柠檬酸钠为还原剂，将氯金酸（HAuCl₄）溶液还原为金纳米粒子（Au NPs）并负载在N-G表面，得到一种新型纳米复合材料——氮掺杂石墨烯-金纳米粒子复合材料（Au/N-G）。通过UV、XRD、XPS、TEM、SEM等手段对该材料的形态、结构、元素组成进行分析，结果表明，该方法可以成功制备Au/N-G。

With low-cost industrial material (NH₄)₂CO₃ as stabilizing agent and nitrogen source,nitrogen-doped graphene sheets (N-G) are prepared by the solid microwave radiation method under hydrothermal conditions.Using the prepared N-G sheets as the substrate materials and sodium citrate as the reducing agent,HAuCl₄ solution is reduced to gold nanoparticles that are supported on the surface of N-G sheets,therefore nitrogen-doped graphene-gold nanoparticles composite material (Au/N-G),a new kind of nanometer composite material,is obtained.The morphology,structure and elements composition of the prepared material are characterized via measures such as scanning electron microscopy,transmission electron microscope,X-ray photoelectron spectra,X-ray diffraction and UV,etc.The results show that Au/N-G can be successfully synthesized via this routine.
