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(HAu Cl4)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。
Nitrogen-doped graphene (N-G) was prepared under hydrothermal conditions by solid-state microwave irradiation with inexpensive and readily available industrial material (NH4) 2CO3 as a stabilizer and a nitrogen source. During the experiment, using NG as substrate material and sodium citrate as reducing agent, HAu Cl4 solution was reduced to Au NPs and supported on NG surface to obtain a novel nanocomposite - Nitrogen Doped Graphene - Gold Nanoparticle Composite (Au / NG). The morphology, structure and elemental composition of the material were analyzed by UV, XRD, XPS, TEM and SEM. The results showed that Au / N-G could be successfully prepared by this method.
