氰化物驱动亚硝酸根捕获强化锌空气电池凝胶/正极界面
Cyanide‐Driven Nitrite Trapping Enables Robustly‐Coupled Gel/Cathode Interfaces in Zinc‐Air Batteries
AI 导读
作者提出用钴基普鲁士蓝类似物（CCN）作为可重构预催化剂，与PVA凝胶电解质组装并在锌空气电池运行中原位电化学活化，CCN重构为片状阵列非晶CoOOH，同时释放的氰化物衍生氮被凝胶网络限域并在PVA/CoOOH界面转化为−NO2基团。
推荐理由
原文给出原位重构界面使表观扩散系数提升至外构建的3.25倍，并展示30%含水下仍保持86.4 mW cm⁻²的功率密度。
创新点
把预催化剂重构时释放的氰化物衍生氮限域在凝胶网络中并转化为界面−NO2分子连接基，用Co–N–O键与氢键同时耦合催化剂与凝胶，使界面离子传输与粘附一并改善。
