We prepared a covalent organic framework containing pyrazine (C=N) and phenylimino (−NH−) groups (HPP-COF) as an anode. The robust covalent linkage and the hydrogen bond network between −NH− and H₂O collectively improve the acid-alkaline co-tolerance and promote the rapid conduction of H⁺/OH⁻ by the Grotthuss mechanism. Thus the HPP-COF exhibits superior cycle stability and rate performance in both acidic and alkaline electrolytes.

适用于酸性和碱性水电池的长寿命高倍率阳极共价有机骨架

我们制备了含有吡嗪 (C=N) 和苯基亚氨基 (−NH−) 基团 (HPP-COF) 的共价有机框架作为阳极。_{-NH- 和 H 2} O之间牢固的共价键和氢键网络共同提高了酸碱共耐受性，并通过 Grotthuss 机制促进了 H ⁺ /OH ^{-的快速传导。}因此，HPP-COF 在酸性和碱性电解质中均表现出优异的循环稳定性和倍率性能。
