"Steering the methanol steam reforming performance of Cu/ZrO2 catalysts by modification of the Cu-ZrO2 interface dimensions resulting from Cu loading variation";
Applied Catalysis A: General, 623 (2021), S. 1 - 15.



Kurzfassung englisch:
On Cu/ZrO2 catalysts, variation of the Cu loading from 0.2 wt% to 80 wt% allows assessing the influence of the
Cu-ZrO2 interface on the methanol steam reforming (MSR) performance by steering Cu particle size and
morphology, revealing the contribution of potential active sites at the interface and the intrinsic relative contributions
of the support and Cu surface fraction. As ZrO2 influences both CO2-selective and selectivity-spoiling
MSR reaction channels, disentangling support-specific effects from the special phase-boundary reactivity and the
intrinsic Cu◦ reactivity is possible by our approach. By choosing a broad range of Cu loadings, a comparison of
the most extreme cases of strong predominance of bulk-like Cu sites (80 wt% Cu) vs. highly dispersed Cu (0.2 wt
%), dominated by interfacial and support reactivity, becomes accessible. Cu (80 wt%)/ZrO2 evolves as the best
MSR catalyst by avoiding adverse support effects and providing a high number of support-wetting bulk-like Cu
sites.
