Two-dimensional carbon nanosheet with controllable types of nitrogen dopants

Caption

Scientists from Fuzhou University obtained a set of nanocarbons through self-assembling guanine molecules. Besides exhibiting intriguing properties, including relatively stable surface oxygen groups and high nitrogen content, the presence of multiple hydrogen bonds in guanine enabled the formation of a two-dimensional nanosheet with controllable types of nitrogen dopants. The nitrogen content can be finely tuned from approximately 5 to 30 percent, while the oxygen content is kept at a consistent 4 percent.
