在文章编号1800005中，王为超，杨静和同事们开发了一种基于激光辐照的创新策略，以选择性地调节NiCo 2 O 4 / N-石墨烯杂化体中吡啶和吡咯氮的相对含量。他们发现，吡啶-N-Co键而不是吡咯-N-Co键负责协同催化作用，从而显着提高了可逆性氧气的电催化活性，并在Zn-空气电池中具有出色的充电/放电性能。

Graphene Hybrids: Identifying the Key Role of Pyridinic‐N–Co Bonding in Synergistic Electrocatalysis for Reversible ORR/OER (Adv. Mater. 23/2018)
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 NiCo2O4/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.
