Аннотация:
Phosphorous-doped graphene nanoflakes (GNFs) were first synthesized by several methods, including pyrolysis of PPh3 solution in toluene, post-treatment of GNFs with H3PO4 and hydrothermal post-treatment of GNFs or oxidized GNFs with PPh3 solution in DMF. The products were characterized by scanning and transmission electron microscopy, low-temperature nitrogen physisorption and X-ray photoelectron spectroscopy. Correlations between composition and structural features were revealed.
