Abstract
The morphologies/dimensions of Au nanostructures can be tailored by merely controlling the reduction degree of graphene oxide surface. Au nanoparticles, long Au nanowires, and semicircular-shaped Au nanoplates are in situ synthesized on slightly, moderately, and highly reduced graphene oxide films respectively, without the need of any templating agent.
摘要
通过控制氧化石墨烯表面的还原程度，可以对 Au 纳米结构的形态/尺寸进行剪裁。在轻度、中度和高度还原的氧化石墨烯薄膜上，分别原位合成了 Au 纳米颗粒、长 Au 纳米线和半圆形 Au 纳米板，而无需任何模板剂。
