In article number 2002464, Shi Chen, Lei Wang, Guichuan Xing, Hui Pan and co‐workers develop a vanadium‐cobalt‐iron trimetal nitride system with greatly enhanced electrocatalytic activity for the oxygen evolution reaction (OER). The metal oxyhydroxide formed in the OER process due to the surface reconstruction and phase transition is the intrinsic active species for the OER. In addition, the promoted oxygen evolution is possibly activated by a peroxo‐like (O₂²⁻) species through a combined lattice‐oxygen‐oxidation and adsorbate‐escape mechanism.

放氧反应：钒-钴-铁三金属氮化物上的表面重建和相变，形成活性羟基氧化物，可增强电催化水氧化作用（能源学报，第45/2020页）

在2002464号文章中，石晨，王磊，邢桂川，潘辉和他的同事开发了一种钒钴铁三金属氮化物系统，该系统大大增强了对氧释放反应（OER）的电催化活性。由于表面重建和相变而在OER过程中形成的金属羟基氧化物是OER的固有活性物质。此外，过氧样（O ₂^2-）物种可能通过结合的晶格-氧-氧化和吸附物逸出机制激活了氧的释放。
