Inside Back Cover: Surviving High‐Temperature Calcination: ZrO2‐Induced Hematite Nanotubes for Photoelectrochemical Water Oxidation (Angew. Chem. Int. Ed. 15/2017)

Fe2O3 nanotubes show extraordinary electrical, optical, and magnetic properties. While high-temperature calcination (HTC) is a key technique to produce high-crystallinity materials, it causes structural damage to nanotube arrays. In their Communication on page 4150 ff., T. Wang, J. Gong et al. present a method for fabricating HTC-resistant Fe2O3 nanotube arrays as photoanodes for water splitting. A ZrO2 shell is deposited onto hydrothermal FeOOH nanorods by atomic layer deposition, and a subsequent high-temperature solid-state reaction produces Zr-decorated Fe2O3 nanotubes.
