Abstract

Invited for this month's cover are the collaborative groups of Dr. Yun Hau Ng at University of New South Wales, Australia and Dr. Yiming Tang at South China Normal University, China. The front cover picture shows ultrathin Co₃ O₄ nanoflakes that are deposited on ZnO nanorods by pulsed electrodeposition. The performance of the nanostructured hybrid Co₃ O₄ /ZnO anode in electrochemical O₂ evolution is better than that of neat Co₃ O₄ . Well-aligned one-dimensional ZnO nanorod arrays are integrated as a scaffold which functions as a "highway" to facilitate improved charge transfer, while the porosity of the anode material allows the penetration of the electrolyte, thus promoting efficient utilization of the catalytically active species.
