Although the study of black phosphorene (BP) and its isomers has attracted enormous attention, the method of synthesizing high-quality samples in a large area is still pending. Here we explore the potential of using the chemical vapor deposition method to synthesize large-area two-dimensional (2D) phosphorene films on metal surfaces. Our ab initio calculations show that BP can be synthesized by using tin (Sn) as a catalyst, while one of its isomers, blue phosphorene (BLP), is very possible to be synthesized by using most other metals, such as Ag and Au. Besides, our study also suggests that the large binding energy between the 2D phosphorene and the active metal substrate may prohibit the exfoliation of the 2D phosphorene for real applications and, therefore, tin, silver and gold are predicted to be the most suitable catalysts for the synthesis of BP and BLP.

催化剂表面上二维磷的选择性生长†

尽管对黑磷烯及其异构体的研究引起了极大的关注，但大面积合成高质量样品的方法仍在研究中。在这里，我们探索了使用化学气相沉积方法在金属表面上合成大面积二维（2D）磷膜的潜力。我们的从头开始计算表明，可以通过使用锡（Sn）作为催化剂来合成BP，而其异构体之一蓝色磷烯（BLP）则很可能可以通过使用大多数其他金属（如Ag和Au）来合成。此外，我们的研究还表明，在实际应用中2D磷光体与活性金属底物之间的结合能很大，可能会阻止2D磷光体的剥落，因此，锡，银和金被认为是最合适的催化剂。 BP和BLP的合成。
