Supported Co–Re Bimetallic Catalysts with Different Structures as Efficient Catalysts for Hydrogenation of Citral (ChemSusChem 4/2019)
The Front Cover shows the different degrees of contact between Co and Re atoms on a TiO2 support, for catalytic hydrogenation of citral. The relative arrangement of Co and Re atoms is a direct consequence of the preparation method used and several morphologies can be produced such as isolated nanoparticles (top image), Janus (second image) and core-shell (Co-Re) (third image) arrangements. The degree of contact between the metals plays a predominant role in enhancing electron transfer and bimetallic interaction, which improves the hydrogenation reaction. However, excessive contact is unnecessary as it leads to shielding of the Co atoms (final image).
