Self-catalyzed growth of large-area nanofilms of two-dimensional carbon.

ABSTRACT: The graphdiyne (GD), a carbon allotrope with a 2D structure comprising benzene rings and carbon-carbon triple bonds, can be synthesized through cross-coupling on the surface of copper foil. The key problem is in understanding the dependence of layers number and properties, however, the controlled growth of the layers numbers of GD film have not been demonstrated, its controlled growth into large-area and high ordered films with different numbers of layers is still an important challenge. Here, we show that a new strategy for synthesizing GD films with 2D nanostructures on ZnO nanorod arrays through a combination of reduction and a self-catalyzed vapor-liquid-solid growth process, using GD powder as the vapor source and ZnO nanorod arrays as the substrate.
