Morphology-dependent interactions of ZnO with Cu nanoparticles at the materials' interface in selective hydrogenation of CO2 to CH3OH.
- A good face: The (002) polar facet of platelike ZnO nanoparticles gives a much stronger electronic interaction with Cu nanoparticles than other facets (see picture; CB=conductance band; VB=valence band) and shows higher selectivity in the catalytic hydrogenation of CO2 to methanol. This finding provides the basis for the rational design of new nanocatalysts for CO 2 hydrogenation. © 2011 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim.
