Carbon Nanosheets: Nitrogen-Doped Porous Carbon Nanosheets Templated from g-C3 N4 as Metal-Free Electrocatalysts for Efficient Oxygen Reduction Reaction (Adv. Mater. 25/2016)

T. Zhang and co-workers report the synthesis of nitrogen-doped porous carbon nanosheets with extremely high nitrogen content and high surface areas using graphitic carbon nitride (g-C3N4) as template, nitrogen source, and porogen. As described on page 5080, the nanosheets exhibit outstanding oxygen reduction catalytic activities which are comparable to commercial Pt/C catalysts in alkaline media.
