Eutectic Syntheses of Graphitic Carbon with High Pyrazinic Nitrogen Content

Abstract

Mixtures of phenols/ketones and urea show eutectic behavior upon gentle heating. These mixtures possess liquid-crystalline-like phases that can be processed. The architecture of phenol/ketone acts as structure-donating motif, while urea serves as melting-point reduction agent. Condensation at elevated temperatures results in nitrogen-containing carbons with remarkably high nitrogen content of mainly pyrazinic nature.

Keywords: deep eutectic mixtures; liquid crystals; porous materials; pyrazinic nitrogen-containing carbon; self-assembly.
