In article number 1800005 , Wei‐Chao Wang, Jing Yang, and co‐workers develop an innovative strategy based on laser irradiation to selectively regulate the relative contents of pyridinic and pyrrolic N in NiCo 2 O 4 /N–graphene hybrids. They identify that the pyridinic‐N–Co bonds, instead of pyrrolic‐N–Co bonds, are responsible for the synergistic catalytic effect, resulting in substantially promoted reversible oxygen electrocatalytic activities, and excellent charge/discharge performance in a Zn–air battery.
