Cover Picture: Morphology Tailoring of Pt Nanocatalysts for the Oxygen Reduction Reaction: The Paradigm of Pt₁₃ (ChemNanoMat 7/2015)

The Front Cover illustrates different Pt13 cluster morphologies that were investigated for the oxygen reduction reaction (ORR). The structural properties, ORR activity, and CO tolerance of five forms were explored to determine which possesses the best combination of catalytic activity and CO tolerance for the ORR. More details can be found in the Full Paper by J. Jellinek, D. Cheng, et al. on page 482 in Issue 7, 2015 (DOI: 10.1002/cnma.201500107). The Inside Cover features metallopolymers, which can be readily embedded in layered silicates, such as montmorillonite. The nanocomposite suspended in silicon oil reveals a distinct electrorheological effect. Application of an external potential results in an increase in the viscoelastic properties.
