We report a facile synthesis of Au nanowires (AuNWs) with a high aspect ratio (l/D) of up to 5000 on a plasma activated graphene template with ultrasound assistance. We demonstrate that the ultrasonication induced symmetry breaking of Au clusters facilitates the growth of AuNWs from the embryonic stages. Furthermore, the growth mechanism of AuNWs is systematically investigated using high resolution electron transmission microscopy (HRTEM), which reveals the unique role of the defective graphene template in directing the growth of AuNWs.

超声辅助石墨烯模板上高纵横比金纳米线的合成及其生长机理的研究†

我们报道了在超声辅助下的等离子体活化石墨烯模板上具有高达5000的高长宽比（l / D）的金纳米线（AuNWs）的简便合成。我们证明了超声诱导的金簇的对称性断裂促进了从胚胎期开始的金纳米线的生长。此外，使用高分辨率电子透射显微镜（HRTEM）系统地研究了AuNWs的生长机理，这揭示了有缺陷的石墨烯模板在指导AuNWs的生长中的独特作用。
