通过将Pt（III）衬底在室温下暴露于苯气体中并将其退火至850 K，在Pt（III）上形成了直径约为5 nm的纳米石墨颗粒。边缘原子相对数目的增加使得能够观察到边缘衍生的电子态。紫外光电子能谱和近边X射线吸收精细结构的测量揭示了位于费米能级的边缘态的出现。
The nanographite grains, the diameter of which was around 5 nm, were formed on Pt(III) by exposing the Pt(III) substrate to benzene gas at room temperature and annealing it up to 850 K. The increase of relative number of edge atoms enabled the observation of edge-derived electronic states. The measurement of ultraviolet photoelectron spectroscopy and near edge x-ray absorption fine structure on the nanographite revealed the appearance of the edge state located at the Fermi level.
