Catalysis under Cover: Enhanced Reactivity at the Interface between (Doped) Graphene and Anatase TiO2
TL;DR: The reactivity of O2 and H2O on top and at the interface of this hybrid system is investigated by means of a wide set of dispersion-corrected hybrid density functional calculations, proving that the "catalysis under cover" is not a general effect, but rather highly depends on the interfacing material properties, on the presence of defects and impurities and on the specific reaction involved.
