      abstract     = {Although Cu/ZnO-based catalysts have been long used for the
                      hydrogenation of CO2 to methanol, open questions still
                      remain regarding the role and the dynamic nature of the
                      active sites formed at the metal-oxide interface. Here, we
                      apply high-pressure operando spectroscopy methods to
                      well-defined Cu and Cu0.7Zn0.3 nanoparticles supported on
                      ZnO/Al2O3, γ-Al2O3 and SiO2 to correlate their structure,
                      composition and catalytic performance. We obtain similar
                      activity and methanol selectivity for Cu/ZnO/Al2O3 and
                      CuZn/SiO2, but the methanol yield decreases with time on
                      stream for the latter sample. Operando X-ray absorption
                      spectroscopy data reveal the formation of reduced Zn species
                      coexisting with ZnO on CuZn/SiO2. Near-ambient pressure
                      X-ray photoelectron spectroscopy shows Zn surface
                      segregation and the formation of a ZnO-rich shell on
                      CuZn/SiO2. In this work we demonstrate the beneficial effect
                      of Zn, even in diluted form, and highlight the influence of
                      the oxide support and the Cu-Zn interface in the
                      reactivity.},
