In article number 1700468, by Mingliang Du and co‐workers, a unique architecture of dual‐phase octahedral CoMn2O4/carbon hollow nanofibers is prepared via a two‐step heat‐treatment process including pre‐oxidation treatment and an Ostwald ripening process. Due to the intimate electrical and chemical coupling, these nanostructures exhibit excellent active oxygen evolution activity with overpotentials...
1D hollow nanostructures combine the advantages of enhanced surface‐to‐volume ratio, short transport lengths, and efficient 1D electron transport, which can provide more design ideas for the preparation of highly active oxygen evolution (OER) electrocatalysts. A unique architecture of dual‐phase octahedral CoMn2O4/carbon hollow nanofibers has been prepared via a two‐step heat‐treatment process including...
