“…Nucleation and growth of Cu has been explored on the polar ZnO (0001) surface, revealing the formation of 3D particles on the Zn-terminated, but 2D-wetting growth on the O-terminated surface due to the larger Cu-O interaction in the latter case. 361,362 On the non-polar ZnO(10-10), mainly the adsorption of hydrogen 35,363 and water 286,311,364 has been studied. Interestingly, binding of a single H-atom per surface unit cell gives rise to a metallization of the initially semiconducting oxide, as demonstrated by STM conductance spectroscopy and HREELS (Fig.…”

“…The origin of the high catalytic activity of Cu/ZnO and the reaction mechanisms of relevant catalytic processes have been debated and remain still unclear [210]. The incorporation of Cu atoms into ZnO may play a role in determining the catalytic activity of Cu/ZnO [13,211]. Here, we present a combined HREELS and hybrid DFT study on a Cu/ZnO model system.…”

“…In addition, the Cu=ZnO system has been largely used as an excellent catalyst for the industrial methanol synthesis. However, key questions on the microscopic mechanism of the reaction are still open and the incorporation of Cu atoms into ZnO may play a role in determining the catalytic activity of Cu=ZnO [11,12].…”
