Graphene/ReSe2 heterostructures have been synthesized on Au foils via a facile chemical vapor deposition route. Interestingly, the second-grown ReSe2 preferentially evolves at the interface between the first-grown graphene and the Au substrate, thus providing a clear example of the confined growth of a two-dimensional (2D) material. The edges and domain boundaries of graphene are proposed to be the preferred intercalation pathways for the ReSe2 precursors.

In this study, we present low-temperature plasma synthesis of vertically oriented hexagonal boron nitride (h-BN) nanosheets with different morphology-maze-like and wavy. The morphological type can be easily and effectively controlled by the deposition temperature. The high thermal stability, oxidation resistivity and significant antibacterial effect of h-BN nanosheets were demonstrated.
