In article number 1702222 , Yida Deng, Tian‐Yi Ma and co‐workers report active site and atomic configuration engineering on a Co 3 O 4 surface through the controllable synthesis of surface‐tailored Co 3 O 4 nanocrystals anchored on N‐doped graphene. An unusual {112} facets enclosed Co 3 O 4 nanopolyhedron with abundant octahedrally coordinated Co 3+ sites exhibits enhanced oxygen electrocatalytic and Zn‐air performance in alkaline electrolytes owing to the optimized adsorption, activation and desorption behaviors of oxygen‐containing intermediates.
