dc.description.abstractThe interfaces of graphene and hydrogenated graphene with 3d atom embedded Pt(111) [Pt-3d-Pt(111), 3d: Fe, Co] substrates have comparatively been investigated utilizing X-ray photoelectron spectroscopy (XPS), near-edge X-ray absorption fine structure spectroscopy (NEXAFS), and temperature-programmed XPS (TPXPS) and desorption (TPD). 3d atoms in the subsurface layer of Pt(111) change the electronic properties of graphene via modifying its p-doping level. Hydrogenation makes graphene pinned to the Pt(111) and Pt-3d-Pt(111) substrates and induces surface segregation of 3d atoms from the subsurface layer into the interface of HGr and Pt-3d-Pt(111). Such a mechanism changes the desorption energetics of hydrogen significantly.
