abstract = {The active chemical state of zinc (Zn) in a zinc-copper
(Zn-Cu) catalyst during carbon dioxide/carbon monoxide
(CO$_2$/CO) hydrogenation has been debated to be Zn oxide
(ZnO) nanoparticles, metallic Zn, or a Zn-Cu surface alloy.
We used x-ray photoelectron spectroscopy at 180 to 500
millibar to probe the nature of Zn and reaction
intermediates during CO$_2$/CO hydrogenation over
Zn/ZnO/Cu(211), where the temperature is sufficiently high
for the reaction to rapidly turn over, thus creating an
almost adsorbate-free surface. Tuning of the grazing
incidence angle makes it possible to achieve either surface
or bulk sensitivity. Hydrogenation of CO$_2$ gives
preference to ZnO in the form of clusters or nanoparticles,
whereas in pure CO a surface Zn-Cu alloy becomes more
prominent. The results reveal a specific role of CO in the
formation of the Zn-Cu surface alloy as an active phase that
facilitates efficient CO$_2$ methanol synthesis.},
