Recently 2D networks of sp2 hybridized B-atoms, called Borophene, have been grown on (111) faces of Cu, Ag and Au and on Ag(110). Borophene, presumably exhibiting highly interesting physical, chemical and electrical properties, does not exist as a bulk layered material, hence it cannot be studied via exfoliation. We investigated the growth of different Borophene phases via bulk segregation of B on Pt(110) by means of scanning tunneling microscopy. Despite the strong anisotropy of the Pt(110) template, different orientations of the triangular Borophene lattice are observed. The vacancy concentration varies, suggesting that it is not only controlled by charge transfer.
