The cover picture shows porous gold nanotubes serving as catalysts for methanol oxidation. The nanotubes were prepared by R. Jelinek and colleagues at Ben Gurion University, Israel, via a simple process combining galvanic displacement of silver by gold thiocyanate, which in parallel underwent spontaneous crystallization and reduction. The porous Au nanotubes exhibited high electrochemically‐active surface area and excellent methanol oxidation catalytic properties, including low onset potential, high oxidation current, good long‐term stability, and recycling capabilities. The favorable catalytic properties are ascribed to the pronounced corrugated morphology of the porous nanotubes. More information can be found in the Full Paper by Jelinek et al .
