Unlocking the Electrocatalytic Activity of Chemically Inert Amorphous Carbon–Nitrogen for Oxygen Reduction: Discerning and Refactoring the Chaotic Bonds

The front cover artwork is provided by Prof. Wei Zhang and Cai Zhang from Jilin University (Changchun, China). The image shows that heat treatment can govern the bonding states and unlock the ORR activity for nitrogen‐doped amorphous carbon, which is an analogy to the beauty of the stained‐glass windows of Sagrada Família Basílica (Barcelona, Spain) revealed by the sunlight streaming through the windows. Read the full text of the Communication at 10.1002/celc.201700106. “The bonding states of chemically inert nitrogen‐doped amorphous carbon are rearranged through mild heat treatment, which enables the “waking up” of an effective oxygen reduction reaction (ORR). The cover picture is used to highlight that the rhythmic variation of ORR activity elaborates well on the subtle evolution of amorphous C−N bonds conferred by the delicate spectroscopy analysis…” Find out more about the story behind the front cover research at 10.1002/celc.201700106.
