Abstract:
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.
