▎ 摘　　要

The CuNi binary alloy can be significant as a catalyst for nitrogen-doped (N-doped) graphene growth considering controllable solubility of both carbon and nitrogen atoms. Here, we report for the first time the possibility of synthesizing substitutional N-doped bilayer graphene on the binary alloy catalyst. Raman spectroscopy, atomic force microscopy and transmission electron microscopy analysis confirm the growth of bilayer and few-layer graphene domains. X-ray photoelectron spectroscopy analysis shows the presence of around 5.8 at% of nitrogen. Our finding shows that large N-doped bilayer graphene domains can be synthesized on the CuNi binary alloy.
