Abstract
Few-layer graphene nanoflakes with the bent edges, diameter of 15–40 nm and thickness of 6–7 graphene layers have been synthesized using MgO-templated CVD growth. Their oxidation by nitric acid led to the high oxygen content of 18 at.%, a third of which was attributed to carboxylic groups. Oxidized nanoflakes were post-doped by nitrogen groups using hydrothermal treatment at 220 °C with ammonia and urea water solutions resulting in corresponding nitrogen content of 7 and 5 at.%. Synthesized and treated materials were characterized by XPS, Raman spectroscopy and electron microscopy.
