abstract = {Room temperature oxygen hydrogenation below graphene flakes
supported by Ir(111) is investigated through a combination
of X-ray photoelectron spectroscopy, scanning tunneling
microscopy, and density functional theory calculations using
an evolutionary search algorithm. We demonstrate how the
graphene cover and its doping level can be used to trap and
characterize dense mixed O–OH–H$_2$O phases that
otherwise would not exist. Our study of these
graphene-stabilized phases and their response to oxygen or
hydrogen exposure reveals that additional oxygen can be
dissolved into them at room temperature creating mixed
O–OH–H$_2$O phases with an increased areal coverage
underneath graphene. In contrast, additional hydrogen
exposure converts the mixed O–OH–H$_2$O phases back to
pure OH–H$_2$O with a reduced areal coverage underneath
graphene.},
