Reduced graphene oxide (rGO) films are decorated with arrays of Au nanoparticles using diblock copolymer micelles by T. D. Chung, B.‐H. Sohn, and co‐workers. On page 2764, they show how decorated rGO films can be transferred to various substrates including carbon electrodes and flexible polymer films without deterioration of the arrays. Decorated rGO films show high electrochemical activity for the oxygen reduction reaction (ORR), and a size‐dependent ORR mechanism is analyzed electrochemically based on a rotating disk electrode.
