摘要

本文合成了三个联吡啶桥接的金属卟啉cop。在碱性介质中，Bpy-CoTNPP在10 mA cm-2下实现了130 mV的低HER过电位，超过了大多数同类产品。这种性能源于协同效应：分层孔隙能够快速传输质量，原子级Co-N位点增强质子吸附，联吡啶桥促进电子转移。本研究揭示了一种优化HER催化的协同机制。

Innovative bipyridine-bridged metal porphyrin polymer for Robust and superior electrocatalytic hydrogen evolution†

Herein, three bipyridine-bridged metallated porphyrin COPs were synthesized. Bpy-CoTNPP achieves a low HER overpotential of 130 mV at 10 mA cm⁻² in alkaline media, surpassing most counterparts. This performance stems from synergistic effects: hierarchical porosity enables rapid mass transport, atomic-level Co–N sites enhance proton adsorption, and bipyridine bridges facilitate electron transfer. The work reveals a cooperative mechanism for optimizing HER catalysis.
