卟啉基有机网络与Nafion非共价交联，解耦燃料电池阴极质子与氧气传输
Decoupled Proton and Oxygen Transport at Cathode Triple-Phase Interfaces via Noncovalently Cross-Linked Biomimetic Nanochannels
AI 导读
研究团队用卟啉基有机网络（H-PorBz）作为离子聚合物改性剂重构催化剂/离聚物/气体三相界面，H-PorBz与Nafion通过NH+-H···SO3–相互作用原位非共价交联形成界面层，将质子传输与氧气传输解耦并抑制磺酸根导致的Pt中毒。
推荐理由
通过非共价交联在阴极三相界面构建仿生纳米通道，将质子与氧气传输解耦，为低铂质子交换膜燃料电池提供了一条界面工程路线。
