Unique Single‐Crystalline Beta Carbon Nitride Nanorods

Growth of single crystal beta carbon nitride (β‐C₃N₄) nanorods (see Figure) has been achieved for the first time through thermal annealing of nanosized carbon nitrides induced by high‐energy ball milling under a streaming flow of NH₃. Most of the nanorods grow along the [001] direction, and the surfaces are defined by (011) and (010) specific crystallographic planes. A possible growth mechanism of the β‐C₃N₄ nanorods is discussed.
