%X The
preparation of model Ziegler–Natta (ZN) surfaces under
ultrahigh vacuum necessitates the activation of MgCl2 films
deposited on a substrate, since these films unexceptionally expose
the energetically most stable but catalytically inactive (001) face.
Here, we present a method to activate MgCl2 films with
the inactive (001) termination, which was based on the chemisorption
of a Lewis base in an analogous way to industrial powder catalyst
preparation. We found that a (001)-terminated MgCl2 film
on Cu(110) was activated into a MgCl2·Lewis base adduct
when exposed to a pyridine vapor at a nearly saturated vapor pressure.
A dynamic response of the MgCl2 film to the chemisorption
and desorption of a Lewis base was uncovered using low-energy electron
diffraction and temperature-programmed desorption.
