The chemical reactivity of single layers of supported graphene (G) is affected by the nature of the underlying substrate: in particular CO chemisorption occurs on G/Ni(111), while graphene on Cu is inert. Here, we demonstrate experimentally that doping of the G layer with nitrogen atoms further increases the reactivity of the G/Ni(111) system...

We use synchrotron radiation-induced core level photoemission spectroscopy to investigate the influence of vacancies, produced by ion bombardment, on monolayer graphene/Ni(111) exposed to CO at pressures ranging from ultra-high vacuum (10-10 mbar) up to near ambient (5.6 mbar) conditions. CO intercalates at a rate which is comparable to the one...

Due to its biocompatibility, TiO2 is a relevant material for the study of bio-interfaces. Its electronic and chemical properties are influenced by defects, which mainly consist of oxygen vacancies or adsorbed OH groups and which affect, consequently, also the interaction with biological molecules. Here we report on an X-ray photoemission...

We investigated the interaction of CO with graphene/Ni(111) and the Boudouard reaction at 3.7 mbar by Near Ambient Pressure X-Ray Photoemission Spectroscopy (NAPXPS), i.e. at one order of magnitude higher pressure than previously explored in-operando conditions. In this regime, CO intercalates under the graphene layer causing its partial...
